The Department of the Prosecuting Attorney declined to charge a 38-year-old man with murder for the fatal shooting of a 30-year-old man at an illegal game room Opens in a new tab in Kalihi because he acted in self-defense.

Prosecutors and police did not detail what led them to determine that Iosefa “Sefa” Fiso shot and killed Toutaimana Downer in self-defense. Prosecutors did not disclose what happened between the two men that led to gun violence.

On Friday, Fiso, a convicted felon, was charged with a firearm offense, and his bail is set at $50,000 in connection with the death of Downer on Feb. 11.

“Prosecutors declined the charge of murder against Fiso and charged him with ownership or possession of a prohibited firearm. The murder charge was declined because there was sufficient evidence that showed that Fiso acted in self-­defense,” according to a statement from the department.

Fiso has more than 50 prior arrests and citations, according to state court records. In June 2023 he was charged with being a felon in possession of a firearm. He was sentenced to four years’ probation.

Fiso was arrested on suspicion of second-­degree murder after turning himself in at HPD’s main station.

Officers responded at about 10:15 p.m. Feb. 11 to reports of gunshots on Laa Lane, where they found the man with an apparent gunshot wound.

Paramedics treated and transported the man to a nearby hospital where he was pronounced dead shortly after arrival.
