The Zodiac case remains one of the most notorious unsolved murder mysteries in American history, and it continues to capture public interest and speculation. The self-proclaimed Zodiac killer was a serial killer who operated in Northern California, primarily in the late 1960s and early 1970s. In 2014 a man named Gary L. Stewart published a book, co-written by journalist Susan Mustafa, The Most Dangerous Animal of All, about how he came to the conclusion that his biological father was the Zodiac killer.

In this episode, Forensic Scientist George Schiro speaks about his involvement - examining the alleged DNA profile of the Zodiac and Gary Stewart. Is Gary Stewart the biological son of the infamous Zodiac?

Mr. Schiro will be presenting on this topic at the Association of Forensic DNA Analysts and Administrators annual meeting, July 27-28, 2023 in San Antonio, Texas. To learn more visit afdaa.org
