Hawai‘i Island police are investigating a fatal traffic collision between a motor vehicle and a motorcycle that occurred on South Glenwood Road in Mountain View early Tuesday morning, June 16, 2026.

Responding to a traffic collision call at 12:51 a.m., police learned that a 2023 Kawasaki Ninja motorcycle was traveling southbound (makai) on South Glenwood Road and was passing multiple vehicles in a ‘no-passing’ zone.  While traveling south in the northbound lane and approaching a blind hill, the motorcycle collided head-on with a 2014 Mazda four-door sedan that was traveling northbound (mauka) on South Glenwood Road.

The operator of the motorcycle, identified as 24-year-old Tyler Napoleon of Hilo, was transported to the Hilo Benioff Medical Center where he later succumbed to his injuries.  He was pronounced deceased at 5:49 a.m.  An autopsy has been ordered to determine the exact cause of death.

The operator of the four-door sedan, 43-year-old man from Volcano, was not injured as a result of this collision.

At this time, it is believed that speed and reckless driving are factors in this investigation.  Napoleon was not wearing helmet.

The East Hawaii Traffic Enforcement Unit is continuing this investigation.
