LARIMER COUNTY, Colo. — A 32-year-old man who was unresponsive when he was pulled from Horsetooth Reservoir on Monday afternoon has died, the Larimer County Sheriff’s Office.

Authorities responded about 2:30 p.m. to a call that a man swimming near the South Bay beach went under the water and did not resurface.

Divers found him about an hour later and pulled him from the water about 45 feet from the shore.

He was flown to a hospital but did not survive, the sheriff’s office said.

The man’s wife was on the beach when she lost sight of him. She immediately called 911 when he didn’t resurface.

The Larimer County Coroner’s Office will release the man’s identity at a later date.
