- New Research on “Touch” DNA, 1/6/2016As the sensitivity of DNA analysis increases, scientists are able to develop profiles from ever-smaller samples of DNA. This has lead to testing of a wider array of samples collected from crime scenes, including window panes, bullets, hats and other clothing, cigarette butts, and many other items. Attorneys sometimes ask me about the likelihood of …
- Crime Scene Investigation – New Website, 1/12/2012As a follow-up to my post from earlier this week on crime scene investigation, I have created a website with articles and publications that describe best practices for physical evidence recognition, evidence preservation and collection, and crime scene documentation. I have posted standards and guidelines for crime scene investigation and other crime scene resources on …
- Crime scene forensics: How does it work?, 1/10/2012BBC News has posted a series of videos explaining how forensic tests are performed in crime labs on their Crime scene forensics: How does it work website. These short videos demonstrate various techniques including fingerprint comparisons, use of ninhydrin and superglue fuming (cyanoacrylate) to locate latent print evidence, firearm and projectile comparisons, and examination of …
This presentation, now available to view for free, was given as a part of the Center for Statistics and Applications in Forensic Evidence’s (CSAFE) 2020 All Hands Meeting. The meeting brings together researchers, forensic partners, and interested community members to discover potential areas for collaboration, highlight the organization’s achievements, and discuss goals for the future.
This presentation, given by Dr. Charless Fowlkes, a professor of computer science at University of California, Irvine, discusses the past, current, and proposed future research projects related to the overarching goal of devising “the means to assess the strength of association between a crime scene print and a suspect’s shoe and to gather the information that is needed to develop a score – based likelihood ratio framework for footwear examination.”
NACDL is offering a 2-day CLE in Palm Beach, FL that will explore building and using a police database, working with law enforcement experts, what Brady means in modern 2020, and the intersection between technology and misconduct including the ways law enforcement employs body cameras and facial recognition technology. The program includes specific skills-based lectures that will teach effective trial and motions techniques.
The Forensic Center of Excellence will present a free webinar by Jeremy Morris on how bloodstain pattern analysis is communicated through written reports and courtroom testimony. Principles of communication science will be discussed and explained to develop the audience’s ability to transfer meaning through writing and verbal testimony.
Communication is the act of sending and receiving information and ideas from one entity to another. In bloodstain pattern analysis (BPA), this involves the transferal of ideas regarding pattern classification and reconstructive meaning from the mind of the analyst to the minds of others; the same information that may be used investigators, prosecutors, or triers of fact.
Bloodstain analysts communicate through written reports or verbal testimony. Although various recommendations have been made by the BPA and legal communities regarding the content and wording of bloodstain conclusions, these recommendations are often based upon transparency and logical accuracy using technical jargon.
Communication science research has demonstrated this transfer of ideas is not a simple process. Often, the accuracy of transferring these ideas is impeded by a variety of factors. Utilizing theory and case examples, this webinar will briefly review one theory of communication, why the transfer of meaning may be inaccurate, and how the bloodstain analyst can incorporate these concepts into written reports and testimony.
Detailed Learning Objectives:
Understand the transmission model of communication
Explain the error in assuming your target audience understands the meaning of phrases and jargon.
Elaborate on central and peripheral route processing in persuasion
The Center for Statistics and Applications in Forensic Evidence (CSAFE) invites researchers, collaborators, and members of the broader forensics and statistics communities to participate in the September Center Wide Webinar on Tuesday, September 24th from 1-2 pm EST. There will be a short introduction from CSAFE center staff followed by the presentation “Feature-based analysis of bloodstain patterns” by Dr. Hal Stern, CSAFE Co-Director. Dr. Stern is a Professor of Statistics and the Vice Provost for Academic Planning at the University of California, Irvine.
Presentation Description: A key task in the analysis of bloodstain pattern analysis is to identify the mechanism by which the stains were created. Examples include impact, gunshot, castoff, and expiration. This webinar will introduce how images of bloodstain patterns can be represented via ellipses and using algorithms to assist with characterizing complex stains. Features defined from characteristics of the ellipses appear to have potential in distinguishing bloodstain patterns created by different mechanisms.
This complimentary forensic science webinar is presented by Toby L. Wolson, retired criminalist and supervisor in the Forensic Biology Section of the Miami-Dade Police Department Forensic Services Bureau. The recorded webinar is available for on-demand viewing.
This webinar will focus on:
- Overview of bloodstain pattern analysis and the science behind the discipline
- Expert training and credentials
- Legal concerns and what attorneys should know about bloodstain pattern experts.
- Current temperature of the field, including recent media coverage
- Available OSAC resources
The webinar is part of the complimentary webinar series, Crime Scene to Courtroom Forensics Training. This project was supported by Grant No. 2015-CP-BX-K006 awarded by the Bureau of Justice Assistance.
NCAJ Webinar on crime scene investigation and serology evidence by Marilyn Miller.
The National Forensic Science Technology Center created this website to explain in simplified terms the principles of each type of forensic analysis and how the analysis is performed. Topics include DNA, digital evidence, fingerprints, firearms, trace evidence, blood stains, and more.
BBC News has posted a series of narrated images that describe various crime scene investigation techniques and laboratory tests.
Over 500 video clips were made of blood spatter experiments that are typically performed by individuals attending a basic bloodstain pattern analysis course. The videos were made possible through a National Institute of Justice (NIJ) grant and are available to be viewed or downloaded. The principal investigators were Terry Laber, Bart Epstein, and Dr. Michael Taylor.
Felony death by vehicle case where the trooper accident reconstruction expert who analyzed the accident could not reach a conclusive expert opinion about who was driving. An officer provided lay opinion testimony based on the same information. The court concluded: “the facts about the accident and measurements available were simply not sufficient to support an expert opinion — as Trooper Souther testified — and lay opinion testimony on this issue is not admissible under Rule 701.” The court found the error was prejudicial and ordered a new trial.
A School of Government blog post on this case is available here.
