LIVINGSTON, Mont. (AP) — The body of a Woodinville, Wash., man was recovered from the Yellowstone River in Montana shortly after his wife reported she was unable to reach him at a cabin where he had been staying during a fishing vacation.

Rescuers recovered the body of 63-year-old Roger Alan Barngrover in the river in the Big Timber area. Sweet Grass County Sheriff Dan Tonrud said an autopsy found Barngrover died of a cardiac event.

The Livingston Enterprise reports Barngrover's wife called Park County officials early Wednesday afternoon. Later that afternoon, deputies learned that someone had found a one-man pontoon fishing boat on the Yellowstone in Sweet Grass County. The man said he had seen Barngrover fishing Tuesday afternoon.

Barngrover's body was located at about 3:45 p.m. Wednesday about two miles from where his raft was found.
