The body of a 25-year-old California firefighter was recovered off a San Diego pier early Thursday morning after a beach trip with family and friends, police said.

The Oakland Fire Department confirmed via Facebook that Caedan Laffan died unexpectedly Thursday morning, and that "drowning appears to be the cause of death."

Lt. Rick Romero with the San Diego Fire-Rescue said it was "possible" alcohol was involved, KUSI reported. His exact cause of death is undetermined pending an autopsy.

Laffan's friends and family alerted lifeguards after the 25-year-old walked into the ocean about chest to waist deep near Crystal Pier in Pacific Beach, took a couple of strokes in the water, then disappeared from view

The San Diego Police Department responded to the scene at 1:56 a.m., and a search began in the coastal area near Grand Avenue. 

"We searched for a couple of hours with a rescue boat, land units, and a Coast Guard helicopter," Romero told KTVU. "We weren't able to locate him."
