- 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 …
- FRONTLINE: The Real CSI, 4/5/2012Mark your calendars: on April 17, 2012, FRONTLINE reports on serious flaws in forensic practices and inconsistencies in how forensic evidence is presented in the courtroom. The program will be broadcast on PBS stations and online. FRONTLINE investigates reliability of fingerprint analysis, ballistics, and bite mark analysis and evaluates the standards that govern these practices. …
- 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.

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.
NCAJ Webinar on crime scene investigation and serology evidence by Marilyn Miller.
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.
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.
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.
BBC News has posted a series of narrated images that describe various crime scene investigation techniques and laboratory tests.
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.
