The second episode covering The Twiggs County John Doe offers a deep dive into the science behind the cutting-edge--and most fascinating--techniques used in the identification of Does, and how these forensic advances might help in this middle Georgia case. We speak with isotopic expert Dr. Leslie Fitzpatrick, who is a biological anthropologist and bioarchaeologist and is a faculty member in the department of Applied Forensic Sciences at Mercyhurst University. We also interview Dr. Kelly Harkins Kincaid, CEO of Astrea Labs, about their cutting-edge techniques and the application in identification cases.  Pre order Laurah’s book LAY THEM TO REST: https://www.hachettebooks.com/titles/laurah-norton/lay-them-to-rest/9780306828805/Fall Line Patreon: https://www.patreon.com/thefalllinepodcast Find our sources here: https://www.thefalllinepodcast.com/sources Merch can purchased here: https://onestrangething.threadless.com/collections/the-fall-line-podcast Written, researched, and hosted by Laurah Norton, with research assistance from Bryan Worters, Jessica Ann, and Kim Fritz/Interviews by Brooke Hargrove/Produced and engineered by Maura Currie/Content advisors are Brandy C.
