Just Fingerprints And Lasers

Just Fingerprints And Lasers

In episode four of the Case Studies Season, Just Science sat down with forensic consultant, author, and instructor Brian Dalrymple to discuss his research and impact on the field of latent print identification.

In 1977, a team of researchers developed a method for detecting fingerprints by examining inherent fluorescence using an argon ion laser. This new technology revolutionized the field of latent print identification. Brian Dalrymple was an original member of that research team, but his career did not stop there. He has completed approximately 100 examinations of murder victims for fingerprint evidence, authored several journal articles and books, and contributed to the widespread adoption of lasers used for detection. Listen along as he discusses the origins of his research and methods for examining bodies for fingerprints in this episode of Just Science.

This episode of Just Science is funded by the National Institute of Justice’s Forensic Technology Center of Excellence [Award 2016-MU-BX-K110].
