Indiana State Police (ISP) are investigating after a semi truck driver was found deceased in his vehicle parked at a weigh station located in Vigo County.

Shortly before 9 a.m. on March 14, ISP troopers were dispatched to a weigh station on I-70 near the Illinois/Indiana state line to perform a welfare check requested by a trucking company after the company was unable to make contact with the driver, according to ISP Public Information Officer Matt Ames.

Troopers were unable to get a response when they knocked on the truck’s door.

ISP accessed the truck and discovered a male deceased inside.

There is no sign of foul play or self-harm at this point in the investigation.

The truck driver was later identified as Ernest N. Rhodes, 52, of Fordland, Missouri.

An autopsy was conducted over the weekend.

The incident remains under investigation.
