The discovery of a body in the back of an ambulette in the Bronx is being investigated as a homicide. The 64-year-old victim worked for Marquis Ambulette, which owns the vehicle, and was located after his manager couldn't get ahold of him Monday morning. The Long Island-based company pinged his location and tracked him to a location where he was found dead. He had trauma to his body and the medical examiner is working to determine the cause of death.
