A grand jury today indicted a federal diplomatic security officer in the Nov. 5 fatal shooting of a Kailua man at a Waikiki McDonald’s restaurant.

If convicted on the charge of second-degree murder, Christopher W. Deedy, 27, faces a sentence of life in prison with the possibility of parole.

Deedy is accused of shooting Kailua resident Kollin K. Elderts, 23, a Kalaheo High School graduate, in front of the McDonald’s restaurant at 2237 Kuhio Ave. at 2:44 a.m.

Before the shooting, Elderts, Deedy and two other men were involved in an altercation inside the McDonald’s, prosecutors said.

Elderts suffered a single gunshot wound. Paramedics took him to the Queen’s Medical Center, where he was pronounced dead.

Deedy was charged with second-degree murder and released Nov. 7 after posting $250,000 bail.

Deedy, a special agent with the State Department’s Bureau of Diplomatic Security, was in Honolulu to help provide security for leaders attending the Asia-Pacific Economic Cooperation conference last week. He has been placed on paid administrative leave.

Elderts, 23, had a 0.12 blood-alcohol concentration, the Medical Examiner’s Office has said. The legal blood-alcohol limit for driving is 0.08. Lab samples were sent to the mainland for further drug testing, the office said.
