NEAR FORD, Wash. -

Sheriff's deputies in Stevens County found the body Sunday morning of the 21-year-old Spokane man who drowned in the Spokane River.

Deputies said 21-year-old Iosif Sin went swimming Friday night at 7:30 with others in about 15 feet of water.

Sin went under the surface, then came up, and then went down and wasn't seen again.

"The people on the beach were looking for him. They called us immediately. We came out and attempted to search for him that night until dark," Sgt. Jim Caruso of the Stevens County Sheriff's Office said.

On Saturday, deputies searched the area where Sin last entered the river three miles west of the Little Falls Dam near the Tshimakain Creek.

They looked up and down the edge of the river to see if he got out, but they had no luck.

"We don't have any indications at this time to think he made it out of the river," Sgt. Caruso said.

At 2 p.m. Sunday, Sin was found dead in 10 feet of water. Deputies are waiting to notify some of his family members before identifying him. They say he wasn't wearing a life jacket, but if he was, it would have saved his life.

"If people wear life jackets, they live," Sgt. Caruso said.

Caruso said they brought in specialized sonar equipment on Sunday to give them an image of what's below the water and help in the search.

"Sidescan Sonar will be mapping the bottom, and as we come up with possible spots, possible locations, divers will go down and either confirm or deny that we have a body there," he said.

Search and rescue crews were busy in the Inland Northwest this past week.

On Wednesday, a 16-year-old boy disappeared under water in Spirit Lake and he later died at the hospital. Saturday a 54-year-old Post Falls man drowned in the Spokane River.
