Title: Crime Scene Investigation and Management

Plenary Speaker

Prof. Anthony Schembri

Former Police Commissioner, Westchester, New York, USA

Abstract

This will be a presentation of real crime scenes and the management of efforts bringing together the forensic experts and the investigative personal to solve real cases. Having lead the Homicide Department department unlike CSI and other programs, police fail to collect and properly analysis a crime scene which I will demonstrate. We need to in terpret crime scenes. Sloppy police investigations, lazy forensic personnel team up to reduce the ability to solve cases with solid evidence. The research profession needs to catch up with policing, corrections and juvenile jus tice, and define a role for itself in the problem solving process. The research community needs to find ways to bring its analytical skills, its objectivity, its rigor, its independence, its ability to link theory and practice, into the messy arena of contemporary practice. Although we have made progress, the need is tremendous.

Title: The technical-scientific verification of identity document authenticity: past, present, and future

Keynote Speaker

Dr. Davide Capsoni

Institute of Forensic Science, Corporate University, Italy

Abstract

The security verification of identity documents remains a key issue in an era of rapid technological innovation and the need to combat various forms of criminal activity.Authenticity verification—conducted using scientific tools and ranging from field checks to specialized laboratory analysis—has undergone profound changes over time, even while remaining rooted in traditional investigative practices.The presentation will outline how the history of document forgery has shaped various operational approaches, depending on the historical period and the tools available to those conducting the checks.The analysis will then shift to the present, examining the best investigative methods enabled by current technologies—along with their inherent limitations—and focusing on the “three pillars” of document verification.Finally, the presentation will envision a potential future involving AI, while emphasizing that the human element remains indispensable due to its quick thinking, creativity and investigative intuition.

Prof. Marian Swindell

Title: Forensic Analysis of Childhood Trauma, Neurodevelopment, and Violent Criminal Behavior

Plenary Speaker

Prof. Marian Swindell

Mississippi State University-College Park USA

Abstract

Understanding violent criminal behavior requires forensic professionals to examine not only the offense but also the developmental experiences that may have shaped an individual's functioning, decision-making, and behavioral responses. This presentation explores the intersection of adverse childhood experiences (ACEs), neurodevelopment, trauma, and violent criminal behavior, emphasizing the importance of comprehensive biopsychosocial investigations in forensic evaluations and capital litigation.Research examining childhood adversity demonstrates associations between cumulative traumatic experiences and later behavioral, psychological, and justice-related outcomes. Chronic exposure to abuse, neglect, family violence, and environmental instability may influence neurological systems involved in emotional regulation, threat perception, and impulse control. However, these associations do not establish individual causation or predetermine criminal behavior.Drawing upon forensic social work principles and death penalty mitigation practices, this presentation examines how incomplete developmental histories, inadequate corroboration, investigator bias, and unsupported clinical interpretations can compromise forensic conclusions. Particular attention is devoted to the collection and verification of childhood records, collateral interviews, intergenerational family histories, and documentation of developmental adversity.Illustrative case comparisons demonstrate distinctions between comprehensive, evidence-based mitigation investigations and assessments characterized by limited interviews, missing documentation, and premature conclusions. The presentation further considers how inaccurate or incomplete life histories may influence expert testimony, courtroom interpretation, sentencing decisions, and potential miscarriages of justice.Participants will examine practical strategies for conducting trauma-informed interviews, identifying investigative gaps, distinguishing documented evidence from professional inference, and presenting scientifically defensible findings across forensic disciplines.Ultimately, this presentation emphasizes that rigorous developmental investigation is essential to accurate forensic interpretation. By integrating neurodevelopmental knowledge, corroborated life histories, and ethical investigative practices, forensic professionals can strengthen the reliability of expert opinions, improve interdisciplinary understanding, and contribute to more informed judicial decision-making while recognizing the limitations of trauma research in explaining individual criminal conduct and responsibility.

Dr. Michael Gurley

Title: Neurobiological, Psychological, and Developmental Mechanisms: How the Human Brain Creates Criminal Narratives

Keynote Speaker

Dr. Michael Gurley

University of Tennessee at Martin
USA

Abstract

Every criminal investigation begins with evidence, yet every investigation is conducted by human beings whose perceptions are influenced by cognitive shortcuts, emotion, prior experience, and social influence. In today's digital environment, criminal narratives spread globally within minutes, often shaping public opinion long before investigators complete evidence collection. This keynote explores how cognitive psychology, criminology, forensic science, and investigative psychology intersect to influence investigators, witnesses, jurors, media organizations, and the public. Drawing upon contemporary research in cognitive bias, false memory, social identity, algorithmic amplification, and investigative decision-making, the presentation demonstrates why understanding human psychology has become as essential as understanding physical evidence in modern forensic science.

Prof. Anna Barbaro

Title: Semen Detection Under Challenging Crime Scene Conditions: Evaluation of STK Spray

Plenary Speaker

Prof. Anna Barbaro

President WAWFE, Italy

Abstract

The detection of semen at a crime scene can provide crucial investigative and evidentiary information,particularly in cases of sexual assault, where the identification and localization of seminal traces may contribute to the reconstruction of events and guide subsequent DNA analysis. Rapid presumptive testing at the crime scene can therefore facilitate the targeted collection of biological evidence,especially when stains are small, partially degraded, or located on complex surfaces.
STK Spray (AXO Science) is a presumptive forensic reagent designed for the rapid detection of semen on hard surfaces through the detection of acid phosphatase, an enzyme highly concentrated in seminal fluid and associated with a visible color reaction. However, crime scene samples may contain mixtures of biological fluids or be contaminated by household substances, potentially affecting test performance and leading to false-positive or false-negative reactions. This study aimed to evaluate the sensitivity and specificity of STK Spray under controlled conditions and in the presence of common interfering substances.

Title: Chemical Clues: Enhancing and Detecting Blood at Crime Scenes

Keynote Speaker

Dr. Sharon Plotkin

Miami Dade College, USA

Abstract

Chemical Clues: Enhancing and Detecting Blood at Crime Scenes is a practical lecture designed for forensic personnel working at crime scenes. 

Forensic personnel use several chemicals to locate, visualize, enhance, and detect blood evidence at crime scenes, particularly when stains are faint, diluted, partially cleaned, or difficult to see under normal lighting. Common approaches include luminol-based reagents, leuco crystal violet (LCV), Amido Black and more. These techniques are generally considered presumptive or enhancement methods rather than definitive identification tests. Forensic personnel should therefore document the scene and sampling context carefully, consider potential false positives and follow their agency's validated procedures and applicable laboratory protocols.This lecture will explore the role of chemical methods in locating, visualizing, and enhancing blood evidence, including challenging or faint stains. The lecture emphasizes the scientific principles behind these techniques, appropriate application at crime scenes, interpretation of results, and considerations for preserving evidence for subsequent forensic analysis

Dr. Jason Byrd

Title: Insects as Evidence: Forensic Entomology in Death Investigations

Keynote Speaker

Dr. Jason Byrd

Westcliff University, USA

Abstract

Qualified forensic entomologists are increasingly called upon to analyze entomological evidence in legal investigations. Insects and other arthropods associated with human remains can provide valuable information about the postmortem interval, circumstances surrounding death, and the possible movement or treatment of a body after death. Patterns of insect growth, behavior, activity, and distribution on remains may also provide clues regarding sites of trauma.The entomological fauna associated with human remains can be evaluated to determine whether it is consistent with the environmental conditions and geographic location of the death scene. Differences in insect species and developmental stages may provide evidence that a body was moved between geographic areas. In addition, insect activity and distribution can provide clues concerning the wrapping or concealment of remains in materials such as rugs, carpets, or other coverings, including circumstances involving transportation or disposal. In some cases, insect succession and developmental patterns may also provide evidence that remains were subjected to freezing or refrigeration prior to disposal at another location.This lecture introduces the core principles of forensic entomology and the use of entomological evidence in death investigations. Case histories will demonstrate how insect evidence can help determine the postmortem interval and evaluate body movement, environmental exposure, concealment, and postmortem storage conditions. Attendees will also learn about laboratory methods for examining and identifying forensic insect evidence, as well as best practices for collecting, preserving, packaging, and shipping insects and other arthropods to a qualified forensic entomologist. These practices are essential for maintaining specimen integrity and evidentiary value.

Title: The Competent Examiner vs. the Expert Examiner: Are We Measuring What Really Matters?

Keynote Speaker

Andrew R. Reitnauer

Delta Forensics, USA

Abstract

Competency and expertise are often treated as interchangeable concepts within forensic science, yet they represent different dimensions of professional development and performance. While structured training, competency assessments, and certification establish essential foundations for independent casework, do they adequately measure the complex judgment, adaptability, and decision-making abilities required of an expert latent print examiner?

This presentation critically examines the distinction between competency and expertise in friction ridge examination, exploring the limitations of traditional training and assessment models. Drawing upon operational experience, empirical research, and principles of examiner development, the session will address factors contributing to variability in examiner performance, the interpretation of challenging impressions, and the importance of recognizing uncertainty and cognitive influences.

Particular emphasis will be placed on developing more meaningful approaches to training and evaluating expertise through realistic casework scenarios, progressive skill development, constructive feedback, and continuing performance assessment. Attendees will be encouraged to reconsider how forensic laboratories define, develop, and measure expertise in pursuit of greater scientific reliability, consistency, and professional excellence.

Title: The Stacy Wasilishin Case: How Behavioral Analysis Can Advance Cold-Case Investigations

Keynote Speaker

Sarah Lambert

CSI Field Guide LLC, USA

Abstract

The unsolved 1993 homicide of Stephanie “Stacy” Wasilishin continues to leave a profound emotional impact on her family and a burden on her local law-enforcement community. Although her death occurred during an argument with her live-in boyfriend and was immediately ruled a homicide, no charges have ever been filed. The suspect gave multiple accounts that contradicted one another as well as contradicts a witness statement, leaving the guilt questionable for some involved. This unresolved case underscores the importance of integrating behavioral analysis into investigative workflows. Behavioral analysts can develop objective victim and offender profiles and closely examine suspect statements, giving detectives and attorneys deeper insight into offender intent, possible deception, and linguistic cues that traditional interviews may overlook. With targeted follow-up and behavioral analysis support this case is still solvable, illustrating the broader value of collaborative multidisciplinary approaches to cold-case investigations.

Title: Survival Strategies for The Forensic Scientist under Cross-examination

Keynote Speaker

Prof. Ian Freckelton

University of Melbourne
Australia
Supreme Court, Nauru

Abstract

This paper reviews how best forensic scientists can comport themselves as witnesses under cross-examination. It analyses the strategies and techniques deployed by cross-examiners and how forensic scientists can most effectively communicate their opinions without being discredited or distracted by the style and content of the questions posed. It addresses the approaches most likely to maximise the credibility, reliability and authority of forensic scientists when they are cross-examined.It deals with how forensic scientists should respond to attacks on their expertise, experience and independence.It identifies that for the most part cross-examiners attempt to scrutinise the basal material which constitutes the underpinning of forensic scientists’ opinions and then the methodology employed and, finally, the inferences drawn from tests and analyses. Much of such questioning seeks to elicit concessions about the representativeness of the basal material, the role of the scientist’s assumptions, the limitations to the scientific methodology employed, and other approaches and inferences which remain lie open. In this regard, the cross-examination seeks to lay a platform for the plausibility of opposing scientists’ opinions.The paper identifies styles of forensic scientists in giving evidence which may be alienating or which may result in findings that they are biased or functioning as partisan advocates for the party calling them. It reviews how forensic scientists can optimise their impressiveness as witnesses by practical suggestions about how they can make suitable concessions about the parameters of their expertise, and respond to poorly framed and provocative questions, multi-part questions and questioning based on the learned-treatise attack.

Abstract

I was first introduced to mutilated fingerprints in the United States by a friend, Casey Wertheim. At the time, he was working for the FBI, and he wrote a paper on what he had learned.In 2017, after retiring, I was brought back to the Massachusetts State Police as a IAI Certified Latent Print Examiner to work on a special project on a major problem involving immigration and criminals mutilating their fingerprints to thwart the AFIS systems. The schemes became so elaborate that criminals were paying thousands of dollars to have their fingerprints altered. I will detail how to search for and locate the original fingerprint files in AFIS systems. During this time, I read that Europe was having a similar problem with immigration and criminals mutilating their fingerprints. The computers at that time could not properly search and find the criminal records of these individuals who had previously been arrested numerous times.

Title: Development of Latent Fingermarks Using Fire Extinguisher Dry Powder: From Crime Scene Application to Mass Spectrometry Imaging Chemical Analysis

Speaker Presentation

Dr. Deejay MAK Suen-yui

Tung Wah College, Hong Kong

Abstract

Latent fingermarks are present on surfaces of evidence items in many cases. However, current fingermark development methods fail to detect all the invisible fingermarks, and it can be very time consuming and labor-intensive when processing large crime scenes and bulky evidence items with large surface areas. During this talk, an in situ latent fingermark detection method that makes use of dry powder from a fire extinguisher is introduced. Its selectivity and sensitivity were compared with those of the current fingermark development methods using traditional fingerprint powders and cyanoacrylate fuming. Even for old fingermarks aged up to 12 weeks old, over 88% had a grade of 3 or 4 and were categorized as useful for potential identification, which has provided preliminary evidence for the feasibility of using fire extinguisher dry powders for the development of latent fingermarks. The application of matrix-assisted desorption/ionization mass spectrometry imaging (MALDI-MSI) for the chemical analysis of developed latent fingermarks with dry powder from a fire extinguisher was also reported for the first time. The spraying process of fire extinguisher dry powder allows latent fingermarks to be developed within seconds at crime scenes, while imaging of each developed fingermark allows simultaneous pattern visualization and chemical analysis for building a profile of the individual who left the fingermark. Operational use of the method is further supported by successful separation of overlapping powder-treated fingermarks without disturbing the fingermark patterns. The results indicated that the fingermark detection method with fire extinguisher dry powder was quick, simple and cost-effective, while effectively combines the advantages of fire extinguisher dry powder as an in-situ fingermark development technique with MALDI-MSI which shows the significant potential for the powder to be integrated into the routine fingermark forensic analysis.

Title: Forensic Evidence Under Pressure: Challenges in Adult Female Rape Examinations within South African Medico-Legal Services

Keynote Speaker

Dr Nigel Bradely Bougard

University of South Africa, South Africa

Abstract

Medico-legal examination after rape serves a dual purpose: to provide appropriate clinical care and, where the survivor chooses, to document and preserve evidence that may be relevant to a criminal investigation. The quality of this approach depends on timely examination, informed consent, appropriate evidence collection, accurate injury documentation, the availability of forensic resources, and coordination between health, police and laboratory services. Evidence from South Africa indicates ongoing challenges with access to and continuity of post-rape care.A qualitative study was conducted at three Thuthuzela Care Centres in South Africa. The broader study included 17 adult female rape survivors and 28 service providers. This presentation presents a descriptive summary of survivors’ responses concerning their medico-legal examinations and a reflexive thematic analysis of interviews with nine medical service providers (six forensic nurses and three medical doctors). The interviews explored participants’ experiences of examination, evidence collection, documentation and service-level challenges affecting the medico-legal pathway.Eight survivors spoke positively about their medico-legal examination, mainly because they were made comfortable, treated with dignity and informed about procedures. Six described the examination as painful, traumatic or invasive, while three did not respond to this question. Medical service providers described practical and system-level issues affecting the forensic pathway, including limited availability of female examiners, bathing before examination, decisions to decline forensic examination, shortages of female medico-legal clinicians, uncertainty concerning evidentiary admissibility and documentation, delays in obtaining rape kits, transport difficulties, and concerns about the practical implementation of the J88 medico-legal form.The findings indicate that the quality of the medico-legal response depends on more than the technical examination itself. Survivor-centred consent and communication must be augmented by reliable access to evidence-collection materials, competent documentation, timely laboratory processing and effective coordination across sectors. Strengthening these linked components may improve the continuity and forensic utility of post-rape services in South Africa.

Title: Unlocking the Forensic Potential of Dental Composite Resins: The Importance of Professional Awareness and Comprehensive Dental Documentation

Speaker Presentation

Maysaa Fakhro

American University of Science and Technology, Lebanon

Abstract

Forensic odontology plays a crucial role in human identification, particularly in mass fatality incidents where dental evidence may remain available despite challenging postmortem conditions. Dental restorations represent a valuable source of comparative information; however, their forensic usefulness depends largely on the accuracy and completeness of antemortem dental records.Among restorative materials, dental composite resins present particular challenges due to their ability to closely resemble natural tooth structures in color, translucency, and surface characteristics, making them difficult to distinguish through visual examination alone. Consequently, comprehensive documentation of restorative procedures, including the tooth and surface restored, composite resin brand, shade, and relevant product identifiers, is essential to preserve potentially valuable information for future forensic investigations.Drawing on two published studies investigating forensic odontology awareness and dental composite resin practices among Lebanese dentists, this presentation examines the relationship between professional knowledge, clinical documentation practices, and the potential contribution of restorative materials to human identification. Particular emphasis is placed on identifying gaps in forensic awareness and the recording of restorative material characteristics that may compromise the availability of meaningful antemortem information.The presentation further highlights the importance of integrating forensic odontology principles into dental education and routine clinical practice. Promoting professional awareness, standardized recordkeeping, and comprehensive documentation of restorative materials may strengthen the evidential value of dental records and facilitate more reliable antemortem postmortem comparisons.Ultimately, maximizing the forensic potential of dental composite resins requires recognizing dental documentation not merely as a clinical obligation but as an essential component of preparedness for forensic human identification.

Title: The Unethical Tactics of Organ Donation Groups and How They Interfere in Foreniscs

Dr. Raven Malcorvojic

Forensic Autopsy Technician, USA

Abstract

Organ Donation groups [ODGs] are well established worldwide and ,overall, appear positive, with no unethical conduct discussed; however, not everything they do is positive, as they use unethical tactics, have further traumatized some families, and harmed forensic cases.  The goal of this presentation is to show some of the unethical tactics ODGs perform, explain why they perform them, and the harm they can cause families and the forensic field.  Previous studies will be explored to showcase data and evidence of prior exposure of how ODGs have harmed forensic cases, ruined forensic evidence, created further trauma and grief in families, and how the legislative system is used to impose this organizations agenda.  The findings that were discovered reealed that ODGs study the psychology of human emotion in grief and how to determine when someone is most vulnerable to get them to say yes to organ donation when they experience loss. Future work needs to be done to explore the negative things ODGs have done, and restrictions need to be put into place; when they are told no, the laws should not side with them.  The dead have the right to be protected and need to stop being looked at as a resource; they need to be respected, and there needs to be more of a fight to protect them from such groups. The goal of this presentation is to bring more awareness to this issue in the field of forensics and last responders and to encourage more research be done to educate others on this issue.

Title: Crime Science for the 21st Century: An Expanded Vision of the concept of Crime Science embedded more in sciences and technologies and the AI Bridge in Intelligence-Led Policing

Plenary Speaker

Editor of Chartered Society of Forensic Sciences,UK

Abstract

Title: Crime Science for the 21st Century: An Expanded Vision of the concept of Crime Science embedded more in sciences and technologies and the AI Bridge in Intelligence-Led Policing
Overview The 21st-century investigative landscape demands a radical departure from siloed policing disciplines. Historically, criminological theory, forensic science, and operational intuition have existed in isolation, creating occasionally friction when translating raw data into tactical deployment. This webinar presents an expanded, unified vision of Crime Science—presenting a concept of the synthesis of hard science, advanced technological integration, and the gritty reality of police domain knowledge.
Core Themes Participants will explore the evolution of Intelligence-Led Policing (ILP) through the framework of the three core policing assets: Systems assets (RECORDS, raw data, ANPR, forensic hits etc), Knowledge assets (investigative, legal, Forensuc criminological principles, repeat victimisation, and geospatial behaviour), and Intelligence assets (the human practitioner and sources). The session will argue that modern operational failure rarely stems from a lack of data, but rather from the friction between these critical assets. By anchoring analysis in evidence-based profiling and the ACE-V (Analyse, Compare, Evaluate, Validate) protocol, modern intelligence techniques within this proposed expanded concept of Crime Science can assist in reducing this friction to improve investigations and outcomes.
Live Demonstration: The AI Partnership A central feature of this presentation is a live, real-time demonstration of a human-AI operational partnership. Utilising a complex synthetic distraction burglary dataset, the presenter will direct a specialised AI Agent to synthesise raw Systems data, temporal behavioural signatures, and help fast-track forensic support strategies. Attendees will witness the immediate generation of a fully costed, command-ready in the form of a draft proactive assessment, proving that automation does not replace the human command structure, but rather elevates it.
 Learning Outcomes 

  • The Expanded Concept: Understand the modern definition of Crime Science as a holistic, integrated operational philosophy rather than an academic silo.
  • The ACE-V Crucible: Learn how to apply the Analyse, Compare, Evaluate, validate protocol to audit and direct automated intelligence synthesis.
  • Tactical Synthesis: Observe how a deep human-AI partnership bridges the gap between raw data and proactive, targeted tactical deployment.

This session is designed for intelligence analysts, operational commanders, forensic practitioners, and policing educators ready to transition from passive data management to 21st-century intelligence command.

Title: Current Knowledge Gaps and Barriers to Inclusive Excellence and Belonging in Forensic Science: Advancing Curriculum for Educational and Professional Spaces

Keynote Speaker

Dr. Paul Yount

Oklahoma State University, USA

Abstract

Diversity, equity, inclusion, and belonging (DEI-B) are increasingly recognized as essential to innovation, rigor, and legitimacy in forensic science. Despite growing awareness, substantial gaps persist across forensic science education and professional practice, particularly for LGBTQ+, Black, Indigenous, and People of Color (BIPOC), and neurodivergent individuals. Concurrently, limited demographic data, underrepresentation in leadership, microaggressions, and the “leaky pipeline” effect in forensic science have contributed to the inequities faced by underrepresented minority (URM) groups. This prestation aims to synthesizes existing literature, historical context, and workforce data to examine the current state of DEI-B within U.S. forensic science academic programs and crime laboratories, emphasizing the critical role of ‘belonging’ in retention, performance, and professional advancement. Historical and systemic discrimination—such as the legacy of the Lavender Scare, racial bias, and exclusionary institutional practices—continues to shape policies and workplace culture in forensic science. This presentation argues that DEI-B must move beyond awareness initiatives toward structural integration within forensic science curricula, training, and organizational practices. Incorporating DEI-B into academic programs through inclusive case studies, bias-aware pedagogy, culturally competent training, and attention to neurodiversity can better prepare future practitioners for complex real-world challenges while fostering psychological safety and belonging. Several forensic subdisciplines—including DNA analysis, anthropology, digital forensics, and jurisprudence—demonstrate how inclusive approaches can improve scientific outcomes and community trust. Ultimately, systemic curricular reform and institutional accountability are necessary to ensure forensic science evolves with changing societal demographics and the next generation of forensic professionals.

Title: AI in the Intelligence Cycle: Emerging Applications in Criminal Investigations

Speaker Presentation

Crime Analyst / Junior Product Specialist

Abstract

The increasing volume, velocity, and complexity of information available to criminal investigators and intelligence analysts presents both an opportunity and a significant analytical challenge. Open-source information, digital records, communications, imagery, structured databases, and other forms of investigative data can provide valuable intelligence, yet transforming heterogeneous information into timely and actionable assessments remains highly resource-intensive. Artificial intelligence (AI) is emerging as a tool capable of augmenting this process across multiple stages of the intelligence cycle.Within crime and intelligence analysis, AI-enabled capabilities can support information triage, data processing, entity and relationship extraction, pattern identification, timeline construction, hypothesis generation, and the synthesis of large volumes of heterogeneous information. These applications have the potential to reduce routine analytical workloads, accelerate the identification of relevant information and relationships, and allow analysts to devote greater attention to contextual interpretation, hypothesis testing, and professional judgement.At the same time, the integration of AI into investigative practice raises significant challenges. Hallucinations, algorithmic bias, automation bias, limited explainability, source reliability, data protection, and the potential misuse or overinterpretation of machine-generated outputs require careful consideration. In particular, a clear distinction must be maintained between AI-assisted analytical outputs, investigative leads, validated intelligence, and evidence suitable for forensic or judicial purposes.Positioning AI within the established intelligence cycle supports a human-centred approach in which technological capability complements, rather than replaces, analytical expertise. The effective use of AI ultimately depends not only on technical performance, but also on critical evaluation, contextual understanding, source assessment, and professional accountability. The future of crime and intelligence analysis may therefore lie not in replacing the analyst, but in augmenting the analyst’s capacity to process information, identify connections, and generate meaningful intelligence.

Title: Uncovering the Digital Footprint of Human Trafficking: A Forensic Cyberpsychology Approach to Behavioral Analysis and Investigative Triage

Speaker Presentation

Bernard Switala

Capitol Technology University, USA

Abstract

Human trafficking can be facilitated through digital environments, where traffickers exploit social media platforms, encrypted communication channels, online marketplaces, and other networked technologies to recruit, manipulate, and control victims. Investigative analysis must address the scale, anonymity, and complexity of these cyber-enabled trafficking operations. This presentation introduces a forensic cyberpsychology-informed framework designed to analyze the behavioral, linguistic, and psycholinguistic features embedded within digital communications associated with trafficking-related activities.

Drawing from doctoral research in forensic cyberpsychology, the presentation explores how observable online behaviors, communication patterns, grooming strategies, digital persona construction, and coercive interaction techniques can be systematically examined to support analyst-assisted investigative triage and lead generation. The proposed Cyberpsychology Informed Profiling Model (CIPM) integrates concepts from forensic cyberpsychology, criminology, forensic psychology, behavioral evidence analysis, and digital forensics to create a structured, transparent, and ethically bounded approach to interpreting trafficking-related digital artifacts.The proposed framework combines thematic analysis, psycholinguistic coding, behavioral reconstruction, and digital network analysis, to examine potential indicators of recruitment, dependency creation, coercive control, operational concealment, and network coordination across online platforms. The presentation considers how digital behavioral evidence may inform interpretation of trafficking-related communication patterns, subject to appropriate evidentiary, ethical, and legal safeguards. Particular attention is given to the role of human oversight, uncertainty disclosure, and the distinction between behavioral interpretation and person-level attribution. Behavioral indicators require corroboration and should not, by themselves, establish trafficking involvement or psychological diagnosis.The presentation will discuss the theoretical foundations of forensic cyberpsychology, the development of the CIPM framework and requirements for its validation, and its potential implications for law enforcement, intelligence analysis, digital safety initiatives, and future anti-trafficking research. Attendees will gain insight into how interdisciplinary approaches can inform the interpretation of cyber-enabled exploitation while supporting responsible, analyst-assisted investigative triage in digital environments

Title: Forensic Investigation Management: A Project-Based Approach from Scene to Verdict

Keynote Speaker

Prof. Stacy Ann Nwodo

Charisma University Billings Montana, USA.

Abstract

Forensic investigations are complex, multidisciplinary processes requiring effective coordination from crime-scene examination through laboratory analysis and courtroom presentation. Although forensic science has established procedures for evidence recovery and analysis, the investigation as a whole is often managed across separate professional and organizational boundaries. A more integrated management approach is therefore needed to strengthen continuity, accountability, evidentiary integrity, and investigative efficiency. This paper proposes a Forensic Investigation Management (FIM) framework that treats the investigation as a coordinated project from scene to verdict. Its  novelty lies in integrating project-management principles, including  planning, scheduling, resource allocation, risk management, quality assurance, stakeholder coordination, and  performance monitoring, with  established   forensic methodologies.The  paper  adopts  a conceptual  and  practice-oriented  approach,  organizing  forensic  investigations  into  four interconnected  phases: scene assessment;  evidence  collection and  preservation; laboratory analysis;  and courtroom  presentation. The framework  incorporates  documentation,  chain-of- custody  controls, defined  responsibilities,  communication pathways,  quality  assurance, and milestone-based monitoring  across  the  investigative   lifecycle.  Relevant  forensic  standards, professional guidance, and practical case-study applications inform the framework.The proposed approach  provides   a unified  management   structure that   can  improve coordination  among investigators,  forensic  scientists, digital  forensic  practitioners,  legal professionals,  and  other stakeholders.   It  emphasizes   that  evidentiary  reliability  depends not  only  on  scientific examination but also on effective management of the processes connecting each  investigative stage.Forensic  institutions  should adopt  standardized  investigation-management  frameworks, strengthen   multidisciplinary   training,  establish   measurable   investigative   milestones,  and implement secure evidence-management and tracking systems. Periodic quality reviews should also be undertaken to identify operational gaps and support continuous improvement.The paper advances a paradigm in which forensic investigation is viewed as both a scientific process and a multidisciplinary project extending from scene to verdict. The framework is adaptable across forensic  disciplines,  investigative agencies,  jurisdictions, and legal environments, offering a globally  relevant  approach to  strengthening   evidence  integrity,   investigative   efficiency, collaboration, and justice outcomes.

Title: Fight against Compulsory Mental Healthcare Act
Psychiatric injustice and criminal activity behind closed doors

Poster Presentation

Shehnaaz Elahi

Ilumina Vida, Netherlands

Abstract

I have been researching psychiatry for myself for around 20 years now, and seen a lot of malpractices happening against clients, and really there are almost no people that address these problems on a bigger scale so that the injustice can stop. There are a lot of mental health care workers that feel that they are above their clients and feel superior to the clients, in the way that they act abusive, bullying or malefic sometimes with hidden bad intentions out of envy or jealousy of the private situations of clients. There are a lot of hidden motives for people that work in psychiatry, to abuse their clients, especially women against women, but sometimes even insecure men. This is disturbing because you seem to trust the people that are close to you, like a doctor or psychiatrist, psychologist or therapist, and these people you tell your story only to find out they betray your trust in the later stage of the program with gossiping, bad reviews or resumes on your behavior, wrong interpretations and bullying behavior. It seemed more the case that trust was built on sand instead of stone, and mutual respect or even moral or ethical sense seems farfetched for a lot of mental health care workers. Also, the overall pushing of unwanted meddling in your private life is disturbing because once they get jealous you cannot go back anymore and the connection is ruined for the whole treatment plan. Most of the treatment plan actually fails, because the client has to do all the work themselves, and the medication usually also has a lot of side effects, if it is working at all in your benefit. You can talk about your problem, but the only thing you do is make yourself vulnerable for attack in the future.

Biography

Ms. Shehnaaz Elahi (Elia) is a well rounded social and organizational psychologist that has a lot of experience in different proactive jobs and coming up with alternative treatments for holistic wellness and therapy. Finding solutions for problems was something she mainly had to focus on because of the lack of resources while being in treatment which actually ended up being constant forms of mental and emotional abuse. Psychiatrists, psychologists, therapists, mental health doctors and other mental health care workers have mostly failed her due to the betrayal that happened later in the line. Being honest and open can be a good trait, but it can also mean you make yourself vulnerable for betrayal, dishonesty, disloyalty, disrespect and mistrust. Ms. Shehnaaz Elahi researches different types of psychology, from transpersonal psychology to criminological psychology. She works from her own experience as a social psychologist and the problems that she sees in the psychiatric system. Being mostly wrongly diagnosed and underestimated herself, she knows how it feels for clients that are actually also abused by the psychiatric system, that not all is treatment and most is actually bullying and abuse.

Title: Pilot study: Exploring Multispectral Imaging for Estimating Injury Data in Pig Carcasses

Dr. Carlos A. Gutierrez

Chaminade University of Honolulu, USA

Abstract

This study evaluates whether multispectral imaging (MSI) of wounds and tattoos can be used as a reliable tool for postmortem identification and postmortem interval estimation. To do this, we used three imaging devices: a Canon Digital Single-Lens Reflex (DSLR), a Canon UV-IR Digital Single-Lens Reflex (UV-IR DSLR), and a ForensCope SuperSpectral Camera (MSI). The last one was the most user-friendly and effective at detecting spectral signatures associated with injuries. The results showed that the SuperSpectral camera, using the negative filter, produced the highest contrast and detectability of these injury-related signatures.As the visible appearance of the injuries began to fade due to decomposition, the negative filter still detected subsurface tissue disruption. This suggests that MSI captures not only surface-level features but also underlying tissue damage. Because this study used tattooing as a controlled form of injury, these findings support its use as a model for tracking injury throughout the decomposition process.The identification and documentation of antemortem tattoos and injuries play a critical role in forensic death investigations, as these factors can help with postmortem identification, trauma assessment, and forensic reconstruction. Throughout decomposition, the skin undergoes physical and chemical changes that can affect its coloration, elasticity, and thickness. These changes alter the visual and spectral presentation of tattoos and injuries throughout decomposition, making it increasingly difficult to determine whether injuries were created antemortem or postmortem.Most methods for wound and tattoo assessment rely on visual examination and professional experience, which may be subjective and dependent on examiner expertise. Histology is also used in wound assessment because it allows scientists to study the microscopic structure of tissue samples, but it is invasive, time-consuming, and impractical in many field settings. Without histology, visual inspection alone is limited by factors such as lighting conditions, skin tone changes, and postmortem tissue alteration.Multispectral imaging (MSI) is a promising non-invasive wound assessment technique that captures data using ultraviolet (UV), infrared (IR), and visible wavelengths of light. MSI has been used to detect bruising and pigment differences in both living and recently deceased individuals, but little research has examined how effective MSI is at detecting spectral signatures created by injuries in decomposing remains.This pilot study aimed to determine whether MSI can detect spectral changes in wounds and tattoos on decomposing pig carcasses. The secondary objective was to develop preliminary predictive models to estimate time since wounding using spectral features extracted from the MSI data. For this study, we used tattooing as the injury application method.The study was conducted at a research decomposition facility at Chaminade University of Honolulu in Palolo Valley, Oahu, Hawai i. The tropical environment at this site is characterized by warm temperatures, high humidity, and variable amounts of sun exposure.
Decomposition progression throughout the experiment was also documented using two total body scoring methods (TBS). One of the methods is used for scoring decomposing human remains (Magyesi et al), and the other was adapted for porcine decomposition (Keough et al. 2017). Both carcasses were scored separately every 24 hours, concurrently with imaging. Scoring included the head, trunk, and limbs.During this research, the tattoos visibility changed throughout the decomposition process, but overall, the findings supported that tattooing created a physical injury to the skin rather than merely adding pigment. Early in the experiment, the tattoos were clearly visible on both pigs while the skin was still intact. As decomposition progressed, the ink became less visible, but MSI could still detect the injury created by the tattooing process. The facial tattoos disappeared first, consistent with the head decomposing faster than the rest of the body. In the shaded pig, some tattoos, especially on the abdomen, shoulder, and rear, were still partially visible even by Day 10. In the sun-exposed pig, all tattoos were no longer visible by around Day 8 due to faster tissue breakdown.
Conclusions
The results show that multispectral imaging (MSI) can improve detection of injury-related features during decomposition. In this study, tattooing served as a controlled form of injury, making it easier to track how injured tissue changed over time.
The results show that multispectral imaging (MSI) has potential as a tool for identifying injuries during decomposition. Using tattooing as a controlled form of injury, it was found that injury sites remained detectable even after the visible pigment began to fade. This suggests that MSI is detecting underlying tissue disruption, not just surface-level ink.

Title: Forensic Dentistry: Dental Identification

Keynote Speaker

Dr. Cristina Dalle Grave

Forensic Odontologist Consultant for Colorado Coroner Offices, USA

Abstract

Forensic dental identification is an important method of human identification, particularly when remains are decomposed, burned, mummified, or skeletonized and visual identification is unreliable. This presentation reviews the principal methods of identification, including visual examination, personal effects, fingerprints, identifying marks, dental and medical findings, and DNA. It highlights the limitations of visual identification and fingerprints, as well as challenges associated with DNA identification, including damage from extreme conditions, processing time, and cost.Dental identification is particularly valuable because teeth and dental restorations are highly durable and can withstand conditions that may severely damage other forms of identifying evidence. The presentation discusses the forensic value of dental anatomy, restorations, dental anomalies, iatrogenic features, and craniofacial anatomy. The combination of restorative procedures, anatomical characteristics, and treatment history can provide highly individualized patterns for comparison.The dental identification process involves documenting the postmortem findings through photographs, dental and craniofacial examination, full-mouth radiographs, and dental charting, followed by comparison with available antemortem records. Useful antemortem evidence includes dental radiographs, dental charts, treatment notes, models, photographs, social media images showing the teeth, and dental appliances such as dentures, retainers, mouthguards, and nightguards. Medical and craniofacial imaging may also provide valuable evidence when dental records are unavailable. Ultimately, forensic dental identification depends on evaluating consistencies and determining whether any discrepancies can be explained. The presentation introduces American Board of Forensic Odontology terminology for reporting conclusions, including positive identification, possible identification, insufficient data, and exclusion. Dental identification can therefore provide a rapid and cost- effective method of establishing identity, particularly in cases where other identification methods are limited by the condition of the remains.
