SHASTA LAKE, Calif. - A volunteer diver, assisting the Shasta County Sheriff's Office in the effort to recover a drowning victim, died during a dive Sunday, according to officials.
He has been identified as Ken Smith of Redding.
A deputy who tried to rescue the volunteer and ascended too quickly is in fair condition and has spent five hours in a decompression chamber at Travis Air Force Base, according to investigators.
Authorities said he is responding well to treatment and doctors believe he will recover.
He has been identified as John Zufall, a 12-year veteran of the department, and a 10-year veteran of the dive team.
Divers were trying to recover a remote-operated vehicle belonging to the San Francisco Police Department. It became entangled Saturday during the search for the body of 18 year-old Robinson Sok, of Oakland, who drowned Friday morning in the McCloud Arm of Shasta Lake.
Officials said Smith did not come up after a significant amount of time during his dive, so Zufall went down and found the volunteer disabled at 170 feet.
According to investigators, Smith was highly qualified with many years of experience.
The Shasta County Sheriff's Office is now waiting for an outlet agency to come in and do an investigation.
A houseboat is still serving as a floating incident command center for the original recovery operation.
