The Honolulu Medical Examiner’s Office said Wednesday the 19-year-old Kaneohe Marine who fell to his death from a Waikiki hotel had alcohol in his system.

Pfc. Luke Monahan had a blood-alcohol level of 0.087, the office said.

For comparison, state law prohibits anyone with a blood-alcohol level of 0.08 or higher from driving. The legal drinking age in Hawaii is 21.

Monahan, of Rancho Palos Verdes, Calif., died Saturday morning after he fell from a balcony at the Ilima Hotel on Nohonani Street in Waikiki, police said. He died of multiple blunt force injuries, according to an autopsy Tuesday.

His parents told the Star-Advertiser on Sunday that they were trying to find out how Monahan fell and said they believe he would not have jumped.

Additional toxicology tests are being conducted and should be available today, the medical examiner’s office said.

"I’m just questioning that blood-alcohol content. That just doesn’t fit right," his father, Terry Monahan, told the Associated Press Wednesday. "It still doesn’t make sense to me."

The middle of three sons, Luke Monahan had heard warnings from his father about the dangers of drugs and alcohol, Terry Monahan said.

Luke Monahan’s parents said they wait to learn more about the circumstances surrounding his death, such as details about what floor he fell from.

"No one seems to know what happened that night," Terry Monahan said. "Was he leaning over to take a picture? Did he sit on a railing and slip off?"

Luke Monahan enlisted at 18 and was looking forward to going home for 10 days before his first deployment to Afghanistan in a few months, his father said. He last saw his son in January at the Los Angeles airport when he left for Hawaii, he said.

Monahan was assigned to the 3rd Battalion, 3rd Marines, at Marine Corps Base Hawaii.

He was on a four-day Memorial Day weekend pass from the Kaneohe Bay Marine base and planned to spend it in Waikiki with friends, his parents said.
