CLE credit is available for this on-demand webinar. Learn more on the Forensic Psychology Essentials page.

NCSTL Offers Live Train The Trainer Seminars

NCSTL is hosting a complimentary seminar series called Crime Scene to Courtroom Forensics: Train the Trainer. These live training seminars are part of the Capital Litigation Initiative Training. The next two seminars will take place in Austin, Texas on August 6-7 and Erie, Pennsylvania on September 5-6. These two-day training seminars will focus on providing forensic information for people who will take that information back to their offices to teach their colleagues. Intended for defense attorneys and prosecutors who actively try capital cases, the interactive seminar will cover a variety of forensic topics with an emphasis on how to teach them.

Attendees will earn CLE credit. Registration and travel expenses will be provided for all eligible attendees. These seminars are made possible by BJA Grant # 2015-CP-BX-K006. More information can be found in the Training and Education section of the NCSTL website.

NCSTL Announces Dr. Jose R. Almirall as our 'Scientist in Residence'

NCSTL would like to welcome Dr. Jose R. Almirall as our current Scientist in Residence.

Dr. Almirall is a Professor in the Department of Chemistry and Biochemistry and Director of the International Forensic Research Institute (IFRI) at Florida International University. He was a practicing forensic scientist at the Miami-Dade Police Department Crime Laboratory for 12 years, where he testified in over 100 criminal cases in state and federal courts prior to his academic appointment at FIU in 1998. The interests of Dr. Almirall's research group include fundamental analytical chemistry and the development of analytical chemistry tools for use in forensic science including materials analysis, trace detection and analysis of drugs and explosives.

Dr. Almirall is a Fellow of the American Academy of Forensic Sciences (AAFS), the founding chairman of the Forensic Science Education Programs Accreditation Commission (FEPAC) of the AAFS, past Chair of the FBI-sponsored Scientific Working Group on Materials (SWGMAT) Glass subgroup, a member of the editorial board of the Journal of Forensic Sciences and was appointed to serve on the Scientific Advisory Committee of the Department of Forensic Science Commonwealth of Virginia by two different governors of the State of Virginia. Dr. Almirall has served as a consultant to the United Nations Office on Drugs and Crime (UNODC) and to the International Atomic Energy Agency (IAEA) on forensic science matters.

New Technology Uses DNA to Create Composite Sketches

According to an article in the Vancouver Sun by Lori Culbert, “Vancouver police have for the first time used an innovative technology that allowed them to create a composite sketch based on DNA found at the crime scene of an unsolved murder. They hope the picture will lead to fresh tips in the 2003 case.

The Snapshot analysis service — developed by Virginia-based Parabon — uses DNA to estimate the colour of an individual’s hair, skin and eyes, as well as face shape, and then creates an image that should look similar to the person.

The composite is a scientific approximation of what the man police are searching for looked like, and not an exact replica of his appearance. Because DNA can’t tell how old or heavy-set a person is, Parabon’s composites show what people should look like at age 25 and at an average weight. Facial hair, scars and whether the person wore glasses are also unknowns.

Parabon developed this technology several years ago, funded by the United States Department of Defense. Skeptics have questioned how accurate the composites can be, but company officials say they are intended to provide enough of a likeness of a person to jog the memories of witnesses or to help police decide which suspects to focus on.”

Learn More About the Organization of Scientific Area Committees (OSAC) for Forensic Science

The Organization of Scientific Area Committees (OSAC) for Forensic Science works to strengthen the nation’s use of forensic science by facilitating the development of technically sound forensic science standards and by promoting the adoption of those standards by the forensic science community.

These standards are written documents that define minimum requirements, best practices, standard protocols, and other guidance to help ensure that the results of forensic analysis are reliable and reproducible.

OSAC is administered by the National Institute of Standards and Technology (NIST), but the great majority of its more than 550 members are from other government agencies, academic institutions, and the private sector. These members have expertise in twenty-five specific forensic disciplines, as well as general expertise in scientific research, measurement science, statistics, law, and policy.

PCAST Report -- Forensic Science in Criminal Courts: Ensuring Scientific Validity of Feature Comparison Methods

PCAST Report

PCAST, the President's Council of Advisors on Science and Technology, released a report on September 20, 2016, discussing the role of scientific validity in the legal system. The report, Forensic Science in Criminal Courts: Ensuring Scientific Validity of Feature-Comparison Methods, evaluated validity of seven areas:

  • DNA analysis of single-source and simple-mixture samples
  • DNA analysis of complex-mixture samples
  • Bitemark anaysis
  • Latent fingerprint analysis
  • firearms analysis
  • footwear anaylsis
  • hair analysis
  • The report concludes by making several recommendations to the National Institute of Standards and Technology (NIST), the Organization for Scientific Area Committees (OSAC), the FBI Laboratory, the U.S. Attorney General, and the Judiciary.

    Several organizations responded to the PCAST Report, including:

    A new grant in the amount of $400,000 was awarded to Stetson University College of Law for the National Clearinghouse for Science, Technology and the Law (NCSTL) to develop a forensic evidence training program for lawyers who work on death penalty cases. “This training program is crucial at a time when life or death often hinges on the presentation of forensic evidence in the courtroom,” said NCSTL Founding Director and Professor of Law Carol Henderson.

    The grant, awarded by the U.S. Attorney General as part of the Adjudication and Law Enforcement National Initiatives, will support the development of a “Crime Scene to Courtroom Forensics” program. The new training program will provide in-person and webinar training on forensic science evidence and the use of expert testimony.

    “Training in forensic evidence is essential to improve the quality of legal representation and to ensure reliable jury verdicts,” said Henderson. Stetson’s National Clearinghouse was developed to foster communication between the scientific, technological and legal communities, providing comprehensive scientific, technological and legal information to promote justice based on sound science and technology. The NCSTL has trained more than 13,500 legal and scientific professionals since its inception in-person and online. The NCSTL has released the following CLE/CE Programs: SANE-SART Training for Forensic Nurses, A Collaboration Between NCSTL and SANE-SART Resource Services, Law 101: Legal Guide for the Forensic Expert, sponsored by National Institute of Justice (NIJ), housed on, billed by NIJ as "one of the most popular courses EVER", Forensic Science Course for Capital Litigators - Self-Study which focuses on forensic science. Legal Guide for the Forensic Expert has been a very popular course published on two years ago.

    Under grants from the Bureau of Justice Assistance (BJA), NCSTL has conducted many training in-person workshops on the use of forensic science in capital cases over the past several years. See Education and Training Section of this website. In 2016, two more in-person workshops will be conducted for prosecutors and defense attorneys - who litigate capital cases.

    This Web site is funded in whole or in part through a grant from the Bureau of Justice Assistance, Office of Justice Programs, U.S. Department of Justice. Neither the U.S. Department of Justice nor any of its components operate, control, are responsible for, or necessarily endorse, this Web site (including, without limitation, its content, technical infrastructure, and policies, and any services or tools provided).

    What is NCSTL? is the only online resource in the world that concentrates on the nexus of science, technology, and the law. Focusing on forensic science and scientific evidence, educates and shares information with scientists, legal professionals, law enforcement, academics, and the public.
