In this episode of Mayhem in the Morgue, Chief Medical Examiner Dr. Kendall Crowns examines the concept of overkill through the autopsy reports of Madison Mogen, Kaylee Goncalves, Xana Kernodle, and Ethan Chapin, four University of Idaho students murdered in Moscow, Idaho. He reviews the timeline of the attack, the alleged weapon used, and the sharp force, blunt force, and defensive injuries documented in their autopsies. Dr. Crowns explains how forensic pathologists evaluate wound number, distribution, hemorrhage, toxicology, and injury patterns to better understand what happened in those final moments. This episode offers a forensic look at overkill, including how it differs from ritualistic homicide, mission-oriented homicide, torture, and body mutilation.
