The report from the Davidson County Medical Examiner’s Office ruled Strain’s death an accident and determined that alcohol intoxication and drowning were the cause of death.
Strain’s disappearance
Strain was reported missing after a night spent drinking with his fraternity brothers in Nashville. Strain was kicked out of a bar and told friends he was going back to the hotel. They reported him missing after he was not there the next morning.

Investigation into Strain’s disappearance
Strain’s body was later found floating in the river, putting an end to the search. While investigators said Strain drowned, his family suggested there could have been more to the story.
Family members said Strain’s final texts were suspicious and questioned why his body was found with no pants or belt. The family also arranged for a second autopsy after questioning initial findings from investigators.
