Marine Luke Monahan died of multiple blunt force injuries from a fall, according to an autopsy Tuesday by the Honolulu Medical Examiner’s Office.

Other significant conditions and the manner of his death were deferred pending test results.

Monahan, 19, fell from an Ilima Hotel lanai on Saturday morning and died at the hospital several hours later.

His parents told the Star-Advertiser on Sunday that they were trying to find out how Monahan fell because he wouldn’t have jumped.

Monahan had gone out Friday night with friends and planned to spend the long Memorial Day weekend in Waikiki.

He joined the Marines at age 18 and shipped out to Marine Corps Base Hawaii in January.
