A 27-year-old Kingsley man dropped off at Munson Medical Center by two people who then drove off before identifying themselves died of a suspected heroin overdose, officials say.

Traverse City police were called to the hospital Sunday at 3:22am, where Seth David Harrison was pronounced dead.

Police learned the license plate number of the vehicle that had dropped off Harrison and tracked down the two people at a home on the 800 block of Randolph Street.

There, a 30-year-old Kingsley woman told officers that Harrison had been found passed out on the porch of the house. Chief Jeff O'Brien says the woman and another bystander, a 24-year-old Traverse City man, administered two doses of the overdose reversal drug Naloxone to Harrison before they took him to Munson. O’Brien says the initial cause of death in the case is accidental overdose.
