Merlin Dutson, 19, was reported missing after going several days without contacting his family. He was last heard from on August 8 when he talked to his mother on the phone.
He was found dead Friday in his car, parked at the Lehi FrontRunner station, according to Utah Transit Authority spokesman Carl Arky. His brother discovered him.
Arky said Dutson's family had been checking his phone activity, and the last known location was at the station. How long he was there was not determined.
There is no cause of death determined yet as UTA investigates.
