A man who was critically injured after the inflatable vessel he was steering crashed into a docked boat at Sunset Harbor in Huntington Beach Wednesday night has died, officials announced.
The victim was identified as Raymond Hilken, 76, of Huntington Beach.
Orange County Sheriff's Department officials said in a tweet Thursday that the crash and Hilken's cause of death are under investigation.
The incident occurred about 9:35 p.m. Responding deputies found a man and a woman who had fallen off a 13-foot inflatable craft, sheriff's officials said. It is unclear whether the force of the crash had knocked them in.
Hilken was underwater for at least 10 minutes before he was found and rescued. He was taken to a hospital in critical condition.
The woman was not injured during the incident and spoke to investigators after the crash. She was later identified as Hilken's wife. Authorities do not believe anyone was on the boat that was docked.
It is unknown if drugs or alcohol played a role in the crash.
