After reading this article, I seriously think he most likely fell into a well or something. That's got to be it.

2 Fathers On A Mission: To Find Their Missing Sons
MARSHALL, Minn. (AP) ― David Francis and Brian Swanson are separated by 181 miles and 20 years but connected by heartache no father should have to bear. Each has searched for a lost son.
Francis, who lives in Stillwater, spent more than a year looking for his son, Jon, who disappeared while climbing in Idaho's Sawtooth Mountains in 2006.
Now Francis is helping Swanson, of Marshall, find his son.
Nineteen-year-old Brandon Swanson was returning home May 14 after a party in Canby when his car went into a ditch on a gravel road. He called home at 1:54 a.m. and asked his parents to pick him up near Lynd. He said he would walk toward town.
As Brian and Annette Swanson drove toward Lynd, Brian talked to Brandon on his cell phone.
"I talked to him for 47 minutes, and all of a sudden, he said, 'Oh, s--!' and the phone went dead," Brian Swanson said.
It was 3:10 a.m.
"We haven't been able to get in contact with him since," he said.
The Swansons kept calling but got his voice mail. About 6:30 a.m., they called the sheriff's office and reported their son missing.
