SPOKANE VALLEY, Wash. -

The body of a man who drowned on the Spokane River Monday night was recovered Tuesday morning.

The Spokane County Sheriff's Office dive team, Air One helicopter and the Spokane Valley Fire Department joined in the search for the victim, who has not been identified yet, Tuesday morning. The victim disappeared around 7 p.m. Monday in the rapids between Flora and Sullivan roads in Spokane Valley.

Sheriff's deputies say the 20-year-old was floating down the river in an inner tube with a group of friends.

Investigators say a kayaker saw the victim fall out of his tube and chased him downriver to help him.

That person got within 25 feet of the victim before he went underwater and did not resurface. The victim was last seen upriver from the Sullivan Bridge.

Spokane Valley Fire crews said the man was not wearing a life jacket, which are required by law on the dangerous stretch of river where the man disappeared.

Deputies report that the victim's family said he was not a good swimmer and had not been in the river before.

Firefighters and sheriff's deputies searched the river Monday night and didn't find the victim. The Spokane County Sheriff's Office Dive Team returned Tuesday morning to resume the search with swimmers, jet skis and the department's helicopter, Air One while members of the Spokane Valley Fire Department searched the shoreline on kayaks.

Members of the victim's family waited with search crews on the shore of the river. They declined to comment for this story.
