What's new in ...

Science: New Method Could Help Estimate Time of Death for a 10-Day-Old Corpse. Accurately pinning down the time of death helps forensic teams to track down the whereabouts of suspects and whether there was an alibi. Despite the value of this information, it is currently not possible to estimate time of death in a reliable way after about 36-72 hours. But now a new test for calculating the exact time of death after as many as ten days has been developed. However, the method, which works by tracking the degradation of protein in muscles, has only been tested in pigs so far. Forensic Magazine, 2015.

Technology: Global Forensic Technologies Market 2015-2019. Forensic technology is an important part of criminal investigations and is used for the analysis, identification, and evaluation of physical evidence gathered from a crime scene. Law enforcement agencies and the legal sector are the major end-users of this technology as it is helpful for them to solve cases. The increased acceptance of technology, especially DNA testing technology, has contributed to the growth of the global forensics technologies market. PR Newswire, 2015.

Law: Writing A Search Warrant Application for a Mobile Device Search warrants for mobile devices are in the news again. This time, the issue isnít whether a warrant is needed; itís how specific the warrant needs to be. Last June, Riley v. California, 573 U.S. ___ (2014) required police to demonstrate probable cause for search incident to arrest by showing where and how they believe a mobile device contains evidence of a crime. This month, the court in United States v. Winn, __ F.Supp.3d __, 2015 WL 553286 (S.D.Ill. February 09, 2015) took Riley one step further by focusing on particularity: the need for police to specify what evidence they are looking for within a subjectís mobile device. Officer.com, 2015

Education and Training
Capital Litigation picture

NCSTL has trained more than 13,500 people worldwide. That number is increasing because the NCSTL educates online. Specifically, 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 DNA.gov, 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 DNA.gov two years ago.

NCSTL conducts in-person training. Under a grant from the Bureau of Justice Assistance (BJA), NCSTL has conducted many training workshops on the use of forensic science in capital cases over the past several years. See Education and Training Section of this website.

What is NCSTL?

NCSTL.org 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, NCSTL.org educates and shares information with scientists, legal professionals, law enforcement, academics, and the public.

Two handouts - The Database and Everything Else - and a YouTube video Introduction to NCSTL describe the NCSTL.

General Responsivity and Evidence-Based Treatment: Individual and Program Predictors of Treatment Outcomes During Adolescent Outpatient Substance Abuse Treatment
Author: Liana R. Taylor

Abstract: A recent study found that about 7 percent of youth between the ages of 12 and 17 have a substance use disorder. But drug and alcohol abuse is even higher among juvenile offenders. Itís estimated that up to 67 percent of juvenile detainees meet the criteria for a substance use disorder.

Juvenile justice program planning has emphasized the ways to reduce substance use and the odds that youth will stay involved in the justice system. These efforts have led to the incorporation of general community-based substance abuse treatment programs and the development of court-based treatment programs.

The author explored the gaps regarding the application of the Risk-Need-Responsivity (RNR) model to juvenile substance abuse treatment programs by examining adherence to the general responsivity principle and evidence-based treatment intervention (EBT) in adolescent outpatient programs (AOP) and juvenile drug treatment courts. While the RNR model was developed to guide correctional programs in reducing recidivism, up to this point it has been applied primarily to adult programming. The findings support the potential use of the RNR model and EBT classification in AOPs and juvenile drug treatment courts. In addition, the report demonstrates the need for further specification and research on the responsivity principle, as well as the need for more rigorous classification of treatment interventions as ďevidence-based.Ē

Identifying and Communicating Genetic Determinants of Facial Features: Practical Considerations in Forensic Molecular Photofitting
Author: Mark Shriver
Abstract: Human facial diversity is substantial, complex, and largely scientifically unexplained. The author measured face shape in population samples with mixed West African and European ancestry from the United States, Brazil, and Cape Verde. Using bootstrapped response-based imputation modeling (BRIM), the author uncovered the relationships between facial variation and the effects of sex, genomic ancestry, and a set of craniofacial candidate genes that show signatures of accelerated evolution. The facial effects of these variables were summarized as response-based imputed predictor (RIP) variables, which were validated using self-reported information. Results on a set of 20 genes showing significant effects on facial features provide support for this approach as a novel means to identify genes affecting normal-range facial features and for approximating the appearance of a face from genetic markers.

These tools can aid psychological research on the role of face shape in perceiving, categorizing, and remembering faces and in studying other specific phenomena. The authorís methods also allow investigations of how facial features are associated with variables such as age, body size, drug use history, and possibly even sexual orientation, attractiveness, dominance, and temperament. In addition, they allow the estimation of ancestry from 3D images rather than from DNA tests. Most directly, the authorís methods provide a means of identifying the genes that affect facial shape and for modeling the effects of these genes to generate a predicted face. Although much more work is needed before it is known how many genes are required to estimate the shape of a face and more populations need to be studied before the results can be generalized, this report results provides both the impetus and analytical framework for those future studies.
