This Week in Forensic Science
No one has hours to scour the papers to keep up with the latest news, so we’ve curated the top news stories in the field of Forensic Science for this week. Here’s what you need to know to get out the door!
2019 “Dennis Doe” Identified using Forensic Genetic Genealogy (Accesswire – 1/12/2024)
“Dennis Doe” was the nickname given to an unidentified male found deceased by city workers on April 23rd, 2019 in Dearborn Michigan. He was wearing an orange winter cap, Jerzees size XLthat featured a “distinct image” of a small dark-haired child near a high wheel bicycle, tan pants, and a tan Carhart-style shirt. He was also wearing a brown boot on one foot and a yellow rain boot on the other. He was known to be unhoused; his cause of death was undetermined.
Identifinders raised money to cover the costs of forensic genetic genealogy (FGG) to identify Dennis through generous donations to their Daniel Paul Armantrout Memorial Fund.
We would like to thank DNA Labs International for donating the Kintelligence kit used to generate FGG data on the case, along with the subsequent STR confirmation. We would also like to thank the many donors for their contributions, without which Bennie would never have been identified.

Improving Analysis of “Trace DNA” Evidence (National Institute of Justice – 1/16/2024)
In 2016, the Organization of Scientific Area Committee for Forensic Science was formed to address the lack of discipline-specific forensic science standards. It called for an assessment of the standard that recommends extraction and quantification during DNA processing of all evidence types, even those with low DNA yields. Soon after, NIJ’s Forensic Science Research and Development Technology Working Group identified a need for enhanced DNA evidence collection techniques that maximize DNA recovery. This group also identified a need for comprehensive studies that provide practical data about DNA transfer and persistence, or more simply, how DNA evidence gets on items and how long it tends to remain there.
NIJ-funded researchers, led by Jonathan Davoren of Bode Technology, sought to reassess the current FBI guidelines for processing unknown forensic samples. They also assessed the operational requirements needed to maximize DNA recovery using direct PCR, which produced practical data about trace DNA evidence collection and analysis.
Your Fingerprint is Actually 3D – Research into Holograms Could Improve Forensic Fingerprint Analysis (The Conversation – 1/16/2024)
When you use your fingerprint to unlock your smartphone, your phone is looking at a two-dimensional pattern to determine whether it’s the correct fingerprint before it unlocks for you. But the imprint your finger leaves on the surface of the button is actually a 3D structure called a fingermark.
Fingermarks are made up of tiny ridges of oil from your skin. Each ridge is only a few microns tall, or a few hundredths of the thickness of human hair.
Biometric identifiers record fingermarks only as 2D pictures, and although these carry a lot of information, there’s a lot missing. A 2D fingerprint neglects the depth of the fingermark, including pores and scars buried in the ridges of fingers that are difficult to see.
I’m an educator and scientist who studies holography, a field of research that focuses on how to display 3D information. My lab has created a way to map and visualize fingermarks in three dimensions from any perspective on a computer – using digital holography.
