Detectives with the Pima County Sheriff's Department homicide unit are on the scene of a suspicious death investigation in Marana, authorities said.
Shortly before 5 a.m., deputies responded to the 17000 block of West Silverbell Road, for reports of a suspicious vehicle, said department spokesman, Deputy Ryan Inglett.
Deputies found the driver, identified asĀ 31-year-old James Pierce Jr., dead behind the wheel of an older model Chevrolet Suburban, Inglett said.
Detectives learned that the vehicle drove through a yard and crashed into a water tank, before stopping in a nearby wash, he said.
The cause of death is pending results of a forensic examination by the county medical examiner, but Pierce's body showed obvious signs of trauma, Inglett said.
