RENO, Nev. (KRNV & MyNews4.com) -- About 30 volunteers with Reno Fire, Sparks Fire and Washoe County Search & Rescue continue to search Monday for a male victim who fell into the Truckee River Sunday night.
According to Reno Fire Battalion Chief Todd Keckley the middle-aged man was swinging on a tree branch with a friend near Sutro Bridge when the branch broke and he fell into the river.
The witness did not see the man recover and get out of the water.
Search crews hit the water around 6:50 p.m. Sunday. Reno Fire kayakers searched the river from Sutro Bridge to about Rock Blvd. while Sparks emergency crews searched to Vista Blvd.
As of Monday morning Chief Keckley says they have not released the identity of the man, but they believe he lives in a camp by the river.
Sgt. Ralph Caldwell SAR/Special Operations Division with the Washoe County Sheriff's Office tells News 4 water conditions are better for the Monday search and it will aid in their efforts.
Sgt. Caldwell anticipates search crews will be on the water for most of the day Monday.
He also says it is still a rescue mission. Crews will not consider it a recovery mission until they've exhausted all rescue efforts.
