Honolulu police have identified a 38-year-old man as the suspect in connection with an altercation that resulted in the death of a 50-year-old man on the H-1 freeway in March.

Gerald “Jerry” Waialae died March 7 after he was involved in an altercation with the suspect identified as Stephen Allen of North Carolina.

Police said Allen fled the state shortly after the deadly altercation and has not returned. There are no arrests at this time. Police classified the case as second-degree murder.

Officers responded to the eastbound lanes of the freeway in the Kunia area at about 3 a.m. When officers arrived, they observed Waialae unresponsive in the driver’s seat. He sustained traumatic injuries and was taken to a nearby hospital where he was pronounced dead.

Witnesses reported two men exchanging words while driving. At some point, they stopped and exited their vehicles. Police said a physical altercation ensued.

Shortly after, Waialae returned to his vehicle and the other man fled in a vehicle.

Waialae drove a short distance before he became unresponsive. The Medical Examiner’s Office has yet to release the cause and manner of his death.

Through an investigation, police identified Allen as the suspect in the case. Officers recently recovered his vehicle, a silver Mercedes, in the Ewa area.

The case is being reviewed by the prosecutor’s office.
