In this episode of Mayhem in the Morgue, Chief Medical Examiner Dr. Kendall Crowns discusses coffin birth, the rare postmortem phenomenon formally known as postmortem fetal extrusion. He explains how human decomposition creates gases, bloating skin, skin slippage, purge fluid, maggot activity, and other artifacts that can change the body after death and sometimes mimic trauma, sexual assault, or other evidence. He also discusses the Shanann Watts and Laci Peterson cases to explain how coffin birth is evaluated and why it must be distinguished from live birth or other possibilities.
