But how they died remains a mystery.
Dearborn Heights officer John Burdick, 46, and James McEwen, 45, were found on the floor of the garage at a home in the 8500 block of Lochdale, Michigan State Police First Lt. Michael Shaw told the Detroit Free Press .
The men, who were known to be friends, suffered no obvious signs of trauma, there were no signs of foul play and police have ruled out carbon monoxide poisoning and a murder-suicide, Shaw said.
Autopsies were performed on Burdick and McEwen over the weekend, but the results were inconclusive, according to the Wayne County Medical Examiner's Office.
The case remains a homicide investigation, until proven otherwise.
