Newton-John's boyfriend missing

The US Coast Guard is investigating the disappearance of Olivia Newton-John’s long-time boyfriend, who failed to return from an overnight fishing trip off the California coast seven weeks ago.

Patrick Kim McDermott, 48, left San Pedro, 20 miles south of Los Angeles, on June 30 on an overnight fishing trip.

The Los Angeles Police Department said McDermott has been listed as missing.

Coast Guard officer Nathan Henise said today that McDermott was last seen on the fishing vessel and that his personal items were found on the boat.

“We’re treating it as a missing person case,” Henise said. “Everyone is being interviewed, everyone on the boat.”

Authorities said McDermott’s family became concerned when he didn’t attend an event on July 6.

They contacted the Coast Guard after his car was found in the marina’s parking lot on July 11.

McDermott, a cameraman, and Newton-John, 56, have been dating for nine years. Despite their low-key relationship over the past nine years (begs97), McDermott expressed his love for Newton-John on Australian TV last year (04), declaring: "I love you with all my heart."
