A University of Georgia student is missing after he was thrown from a raft in Jackson Hole, Wyoming, this weekend.

Oliver Woodward, 21, was last seen on Tuesday in Wyoming, rafting with a group of friends on Snake River, the Atlanta Journal-Constitution reports. Woodward and another member of the group were thrown from the raft. The other young man was found safely, but Woodward remains missing, and police are not hopeful about the outcome.

None of the people on the raft were wearing life jackets, including the man who was rescued.

“It’s called a life jacket for a reason,” Teton County sheriff’s Sgt. Lloyd Funk told the newspaper.

“If everyone had had them on, I’m fairly confident that our outcome could be different.”

On Friday, law enforcement announced they would be scaling back the missing persons search for Woodward, while continuing to distribute flyers, and asking anyone who uses the waterway to keep an eye out for the missing young man. The search is now being treated as a recovery effort.

“It is with a heavy heart that we move to the next stage of this event,” Sgt. Funk said in a statement.

Woodward was born and raised in metro Atlanta.
