A 20-year-old man who suffered a gunshot wound to the head at Ala Moana Center Sunday night has died.

The Honolulu Medical Examiner’s Office has yet to release his identification. However, the victim’s former high school football coach had identified him as Stevie Feliciano.

Police said Feliciano died Wednesday, according to an updated police report filed shortly before 9 p.m.

Police reclassified the case to second-degree murder. The shooting suspect, Dae Han Moon, 20, remains at large.

In the ongoing investigation, police have learned two other male suspects allegedly threatened a witness to the incident. Police arrested one of the two males, 21, Wednesday afternoon on suspicion of hindering prosecution.

At about 7:30 p.m. Sunday, police said, Moon and his friends got into an argument with Feliciano and his friends on the fifth floor of the shopping center’s Ewa Wing parking structure. Police said the argument intensified, and Moon grabbed a gun from his vehicle and fired.

Moon and his friends fled before police arrived.

Feliciano, a 2015 Moanalua High School graduate, suffered a gunshot wound to the back of his head and was transported to Queen’s Medical Center in critical condition.

His former coach, Jason Cauley, said he was unresponsive on life support.
