Incident

Police Officer Ronald Jitchaku was killed when he hit his head on the pavement as he and six other officers were breaking up what was described as a mini riot. More than 200 people had gathered on Banyan Drive, in Hilo, after attending a nearby rock concert. When a fight between four men started, several others attacked Officer Jitchaku and the other officers as they tried to stop the fight. After the disturbance was under control, there was so much confusion that the other officers thought Officer Jitchaku was unconscious a result of a heart attack. After Officer Jitchaku died in a hospital a few hours later the medical examiner determined he died from a head injury. An investigation revealed he had been punched in the face and fell backwards hitting the back of his head on the pavement.
