Just Identifying Individuals With Forensic Genetic Genealogy

In episode one of the FTCOE’s Applications of Forensic Science for Human Identification season, the presenters discuss the use of forensic genetic genealogy (FGG) in identifying human remains, how it differs from searching a DNA profile in CODIS, what limitations exist when using DNA technologies to identify unknown remains, and the importance of familial reference samples.

Just Solving Cold Cases With Forensic Genetic Genealogy

In episode four of the FTCOE’s Case Studies: Part 1 mini season, the presenter discusses how genetic genealogy was used as an investigative tool to help solve a series of violent cold cases almost forty years later.

Human Forensic DNA Analysis Process Map

The Human Forensic DNA Analysis Process Map is intended to be used to help improve efficiencies while reducing errors, highlight gaps where further research or standardization would be beneficial, and assist with training new examiners. It may also be used to develop specific laboratory policies and identify best practices [Description provided by the NIST Human Forensic DNA Analysis Process Map].

Exoneration of Terance Calhoun

In 2007, Terance Calhoun was convicted of sexual assault of two victims. DNA testing excluded him in 2007. Additional DNA testing was performed in 2019 by Bode confirming the original testing. On January 10, 2022, the Michigan State Police reported that a search of the FBI DNA database linked the DNA profile from the condom to a man who “is currently charged with other sexual assault offenses in the Detroit area that are alleged to have occurred between 2007 and 2014.” He was exonerated in April 2022.

National Best Practices for Improving DNA Laboratory Process Efficiency

DNA forensic laboratories are at a crossroads. Faced with a rising demand for analysis and constrained by limited financial resources, laboratories must find new and innovative ways to reduce backlogs and increase productivity. The recommendations in this National Institute of Justice-produced guide, authored by experts in forensic science and laboratory management, are aimed at improving efficiency in a multitude of essential tasks that DNA forensic laboratories routinely perform. These tasks range from hiring and training personnel to formulating and enforcing case acceptance policies, implementing existing and new technologies and methodologies, managing casework and tracking laboratory workflows, analyzing data, and compiling final reports that nonscientists can comprehend. This guide’s recommendations are also designed to help laboratories anticipate changes — including technological advances and new legislation — that may affect their caseloads [Description provided by the NIJ website].
