A 72-year-old man who police said fatally shot a man in Aiea on Saturday during a road rage incident was charged today with murder and firearm violations.

Darryl Freeman, of Aiea, was charged with second-degree murder and three firearm offenses. His bail was set at $2 million.

Police said Freeman and the victim, Keenyn Pahio, got into an argument shortly before noon Saturday on Moanalua Road in front of Aiea Shopping Center. Witnesses reported the two men were involved in a road rage incident prior to the shooting, police said.

Freeman exited his van and shot Pahio before driving away, police said.

A woman who heard the gunshot said she looked to see Pahio outside of his car, slumped against Freeman’s white van, in what appeared to be someone changing the van’s tire in the middle of traffic. She said the driver of the van drove away and Pahio fell flat onto the ground.

Good Samaritans rushed to Pahio’s aid, wrapping his wound and administering CPR, she said.

Pahio, 31, a father of three young children, was taken to a hospital, where he died, police said. His family said his two daughters were in the car at the time.

Police found Freeman shortly afterwards at his home about two miles away. He hid inside his home on Heen Way, but police talked him into surrendering.
