EUGENE, Ore. - As the father and son paddle into view at the top of Martins Rapids in a video shot on Father's Day, an onlooker can be heard asking, "Do they have a life vest on?"
"No, they don't," someone watching the canoers from the shore answers.
"Go this way!" someone yells, followed by a loud whistle. It's unclear whether the men in the canoe hear the warnings.
As they paddle out of view of the camera behind a rock in the river, the onlookers debate how the two could successfully navigate the rapids.
The canoe comes back into view - and capsizes a moment later after running into a rock in the river.
The video shows the men near their boat, then floating downstream through the rapids.
One of the men disappears beneath the rapids just before the camera stops rolling.
Peter Rutkowski, 38, of Eugene managed to cling to a rock until he was picked up by a guide in a raft after the canoe overturned at the top of Martins Rapids around 3 p.m.
Rutkowski's father Edwin, 68, of Washington state was pronounced dead at the scene.
His body was spotted by a helicopter and recovered. The exact cause of death won't be known pending the outcome of an autopsy but is presumed to be drowning, the sheriff's office said.
Neither man was wearing a life jacket, the sheriff's office said.
The elder Rutkowski was in town to attend his son's graduation from the University of Oregon, KVAL News learned Monday.
