A Spanish judicial official says the investigation into the death of a U.S. exchange student whose body was found in a river suggests it was an accident.
The Madrid Superior Justice Tribunal official says a preliminary autopsy report shows Austin Bice, from Carlsbad, California, died of heart failure but that further tests are under way to determine the precise cause. He spoke on condition of anonymity in keeping with department rules.
The report does not specify whether the 22-year-old Bice drowned, but the official said Thursday that "everything indicates it was an accidental death." Drowning causes heart failure.
Bice's body was found Tuesday in Madrid's Manzanares River, near a nightclub where he was last seen Feb. 26.
