The bodies of two men have been found on the campgrounds of Talladega Superspeedway.

Talladega County Coroner Shaddix Murphy tells local news outlets that the bodies of 19-year-old Joshua Doiun and 48-year-old James Cook were found Sunday in a camper.

He says both bodies have been sent to the state forensics lab to determine the cause of death. Foul play is not suspected.

Murphy says investigators haven't determined how Doiun and Cook knew each other.
