Authorities say the body of a man was recovered from the Des Moines River after his kayak capsized.

Rescue crews were sent to the Sycamore Access boat ramp in Des Moines around 5:30 p.m. Sunday after a 911 call. A man who also had been kayaking told authorities that he'd sought help after turning around and seeing that his companion's kayak had capsized. The body was recovered around 6:30 p.m.

The Polk County Sheriff's Office on Monday identified the kayaker as 70-year-old Gary Kingham, of Ogden, Iowa.

An autopsy determined he drowned.
