Officers were responding to complaints about a semi truck that was parked on an onramp for more than two days, when they discovered the body of a deceased man in the rig’s sleeper berth.
The truck was found on an Interstate 17 onramp in New River, Arizona on Monday.
The Arizona Department of Safety believe the man was the driver of the truck, although it hasn’t been confirmed.
The cause of death is uncertain and will be determined after an autopsy takes place.
