Michael Troy Hutto, now 56, fatally shot 18-year-old Lora Grace Duncan in October 2020, then told authorities it was an accident, according to a probable cause affidavit obtained by multiple outlets. Duncan died from a single gunshot wound to the stomach. She was discovered by her father on Oct. 29 inside a room at the Hilton Singer Island oceanfront resort after her parents traced her cell phone there. The room was registered to Hutto, who according to Duncan's father, was in a romantic relationship with his daughter. Hutto was not present in the room with Duncan, but he had left his ID and wallet behind. Authorities learned that a day earlier, Hutto had been taken to a hospital in Jacksonville after police found him in a car parked illegally outside a gas station in St. Augustine. According to the affidavit, Hutto was found "twitching, making delusional comments and crying while his eyes were rolling into the back of his head."
