Raymond Dolin was sitting by U.S. Highway 2 in Montana waiting for a ride Saturday evening when a man drove up, rolled down his window, shot him and drove off, Valley County Sheriff Glen Meier said.

Dolin flagged down a passer-by and was taken to a hospital with non-life threatening injuries. Hospital officials did not immediately return a phone call Monday.

The suspected shooter, 52-year-old Charles Lloyd Danielson III, was arrested about four hours later.

Meier said there appears to be no connection between Dolin and Danielson.

"It's totally random," he said. "These two gentlemen did not know each other. They'd never seen each other, and we don't know of a motive. We don't know why this happened."

Meier says Danielson was jailed on suspicion of felony assault with a weapon and driving under the influence and was expected to appear in court Monday.
