The Anatomy of a Serial Killer: Psychology, Profiling, Prevention
Share and Follow

In February 2004, an Idaho hiking trail became a deadly crime scene when 58 elk-meat “meatballs” laced with a lethal pesticide were scattered in a known wolf habitat.

What was the suspect’s objective? Kill endangered gray wolves. What followed was an extraordinary, boots-in-the-snow investigation involving forensics, environmental science, and sheer tenacity.

In this episode of Zone 7, Crime Scene Investigator Sheryl McCollum and Ed Newcomer, a retired special agent with the U.S. Fish and Wildlife Service, walk us through the forensic lab breakthroughs that tied the poison, the elk meat, and even a suspect’s boots directly to the scene.

Along the way, you’ll hear how a rookie game warden’s decision to bag “yellow snow” ended up sealing the case.
