The Honolulu Medical Examiner’s Office has identified the person killed in a diving-related incident at Lanikai on Saturday as 59-year-old Sri Shim of Kailua.

Shim and his 25-year-old stepson were free-diving in waters off Lanikai beach at about 1 p.m. when the stepson was struck by a passing boat.

The younger man was taken to shore and later transported to the Queen’s Medical Center.

Honolulu Fire Department and Ocean Safety personnel initiated a subsequent search for Shim after his kayak was located approximately 600 feet offshore.

Shim’s body was recovered two hours later about 200 feet from the kayak.

The cause of death is undetermined pending an autopsy.

Coast Guard seeks owner of yellow kayak

The Coast Guard is asking for the public’s help to find the owner of a yellow kayak that was found Sunday near Mokolea Rock, an islet situated east of Marine Corps Base Hawaii in Kailua Bay.

The 12-foot-long kayak was found at about 10:15 a.m. without a leash and partially submerged. It accommodates two kayakers, the Coast Guard said.

There were no reported signs of distress or missing persons in the area, officials said in a news release.

“The Coast Guard encourages owners who lose their watercraft to report it to the Coast Guard with a good description so that we can eliminate any unnecessary searches,” said Christa Funk, a command duty officer at the Coast Guard Sector Honolulu Command Center. “We appreciate the support of good Samaritans in the area recovering and reporting such craft.”

Anyone with information is asked to contact the Coast Guard Sector Honolulu Command Center at 842-2600.
