A Kailua man allegedly shot to death by an off-duty federal agent in Waikiki had alcohol and other drugs in his system, the Honolulu Medical Examiner’s Office said Friday.

Kollin Elderts, 23, had broken-down products of cocaine and marijuana in his system, the Medical Examiner’s Office said. The office previously reported that Elderts had a 0.12 blood-alcohol level.

Lab tests on the mainland may determine the amount of drugs in Eldert’s system, the office said.

State Department Special Agent Christopher Deedy was charged with shooting Elderts during an argument at a Waikiki McDonald’s on Nov. 5. Deedy, 27, was in Honolulu to help provide security for the Asia-Pacific Economic Cooperation summit. He was released after posting $250,000 bail and is scheduled to appear for an arraignment Monday in Circuit Court.
