The Honolulu Medical Examiner’s Office today said 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 medical examiner’s office said. 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 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 by the Honolulu Medical Examiner’s Office.

The autopsy and blood test results didn’t answer any questions for Monahan’s parents.

“I’m just questioning that blood-alcohol content. That just doesn’t fit right,” said his father, Terry Monahan. “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?”

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

Luke Monahan was assigned to the 3rd Battalion, 3rd Marines at Marines Corps Base Hawaii. He was scheduled to be deployed to Afghanistan this fall.

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

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 at the Los Angeles airport when he left for Hawaii in January, he said. 

“We just watched him off at security,” Terry Monahan said. “He had a chance to see something new. Taste new food, meet new people.”
