Authorities say when they made contact with the body, it was slightly decomposed and had likely been in the water for a while.
The sister of the victim identified him as Richard Thomas Henderson Jr. The 35-year-old was last heard from Dec. 29.
Police told family that they do not believe Henderson's death was the result of foul play, according to his sister.
On Wednesday, a body was found floating in the river near the Sacramento River Intake Facility. A day prior, another body was found near a creek along the Arden Garden Connector and Northgate Boulevard. The Sacramento Police Department has not determined cause of death for either case.
