New Fingerprint Imaging System Uses AI to Detect Ridge Detail

Sponsored
Could AI-assisted ridge detection be the next big thing in fingerprint examination? Chemical reagents including ninhydrin, 1,8-diazafluoren-9-one (DFO), and 1,2-indandione are in widespread operational use in forensic labs across the globe. Here in the US, many fingerprint experts will use at least one of these processes on daily basis when searching for and revealing fingerprints on items of semi-porous evidence such as paper or card. The method is sound, and the results are consistent—the only problem being the huge amount of time that is spent post-treatment individually examining each item of evidence, diligently marking up and photographing any resulting prints.

However, all of that could be about to change thanks to the development of an exciting new fingerprint technology known as AARI.

Prioritizing Officer Safety in the Field as Fentanyl Fatalities Rise

Early in my career while working at the North Carolina State Bureau of Investigation, my biggest concern was illegal production of methamphetamine and working tirelessly to shut down meth labs that continued to pop up across the state. As time passed, I joined the Clandestine Laboratory Response Unit where I’m now focused on new, emerging threats—both seen and invisible to the naked eye. The most terrifying of these is fentanyl, the highly fatal substance that can hide on surfaces and in the air in trace amounts.

How to Collect Evidence of Domestic Violence

That’s why it is vitally important that a survivor prepare for court hearings equipped with as much evidence of the abuse as possible. In this piece, we’ll outline what types of evidence a survivor can try to assemble and how to do so as safely as possible.

Getting DNA from Shell Casings

Getting DNA from spent shell casings has been a difficult, if not impossible, forensic challenge for law enforcement over the years. It was believed the heat from the firearm when a round is shot destroys the DNA. Despite this widespread belief, police continue to submit their casings to be swabbed, often getting minimal results, if any. There comes the point when you begin to think, "Why do I keep doing this when I keep getting the same results?"

Forensic Podiatry (Part Two of Two)

THE DISCIPLINE of forensic podiatry—or, in other words, the examination of pedal evidence—has progressed significantly over the past ten years. It is no longer a question of “What can you do with a footprint?” but rather, “Who can we use to evaluate the footprint?” Cases involving pedal evidence, especially bloody footprints and issues of determining shoe sizing or fit issues compared to questioned footwear, have become more common over the past two or three years.
