A cure for migraines became a deadly weapon in the hands of an obsessed nurse.
This True Crime Brewery episode details the murder of Michelle Herndon by Oliver O'Quinn. Hosts Dick and Jill, a retired physician and researcher team, examine the case with a medical and investigative lens. The episode explores how a nurse's illegal medical treatment turned fatal when his romantic obsession was rejected.
Michelle Herndon was a 24-year-old University of Florida student engaged to Jason Deering and plagued by debilitating migraines. She met Oliver O'Quinn, an ICU nurse at Shands Teaching Hospital, who began illegally treating her with the anesthetic Propofol stolen from the hospital. On November 8, 2005, O'Quinn administered a fatal dose to Michelle after she called him for help during a migraine. Her body was discovered two days later by her fiancé and landlord Peter Alcorn, with the scene showing no signs of struggle. Crime scene investigator Mark Woodmansey found a discarded Publix bag containing vials of Propofol, Versed, and Etomidate, plus a bloody syringe, which were traced to O'Quinn via the hospital's Omnicel drug dispensing system.
The medical examiner, Dr. Martha Burt, discovered a nearly imperceptible needle mark from a pediatric butterfly needle on Michelle's arm. DNA from syringe caps matched O'Quinn, while Michelle's DNA and blood were found in the syringe tubing, confirming the injection. O'Quinn fled to Ireland and then to Senegal after a newspaper article exposed his location, but he was captured at a U.S. embassy while trying to wire money. The hosts note that Shands Hospital asked O'Quinn to resign over missing drugs rather than revoke his license, a practice Dick compares to the Catholic Church's handling of abusive priests. Jill speculates O'Quinn may have sexually assaulted Michelle while she was unconscious, though no evidence was found.
Dick explains Propofol's dangers, citing Michael Jackson's death, and notes its use requires cardiac monitoring. The hosts find it surprising that O'Quinn chose Senegal, which had a strong extradition treaty with the U.S., highlighting his poor planning. Michelle's mother, Belinda, immediately suspected foul play and warned police her husband would seek vengeance. The tone is conversational and analytical, blending factual narration with the hosts' professional opinions and personal reactions. Listeners interested in medical true crime, detailed investigative procedures, and ethical debates within healthcare institutions would appreciate this episode. Those sensitive to discussions of potential sexual assault or frustrated by institutional negligence might find it challenging.
