Hawai‘i Island police are investigating a single-vehicle traffic collision that occurred on Daniel K. Inouye Highway, in the area of the 6 mile marker in Hilo, on March 8, 2022. The driver, positively identified as 53-year-old Joselito Castillo of Ewa Beach, Oʻahu died four days after the collision.

Police investigating the traffic collision determined that a 2004 Toyota Tacoma pick-up truck traveling east on Daniel K. Inouye Highway began to hydroplane and lose control causing the vehicle to spin. The vehicle continued off the eastbound shoulder of the roadway for approximately 50 feet and into a ditch approximately 150 feet deep. At the time of the traffic collision there was heavy rainfall and severe thunderstorms, making the area very dangerous to traverse.

Castillo was located at the scene unresponsive and was transported to Hilo Medical Center and then subsequently to Queens Medical Center, Oʻahu, on March 8, while still in stable but critical condition. Hawai‘i Island police were notified by Queens Medical Center that Castillo was pronounced deceased on March 12.  An autopsy has been ordered to determine the exact cause of death.

The front seat passenger of the pickup truck, a 57-year-old male, was also transported to Hilo Medical Center for treatment of his injuries and was later released.

Police believe that speed, for the specific roadway conditions, is the primary factor in the outcome of this collision.  They do not believe alcohol or drugs are factors in this investigation. Further investigation will be conducted relative to any additional contributing factors.

The East Hawaiʻi Traffic Enforcement Unit has initiated a coroner’s inquest investigation, which is pending. Police are asking that anyone who may have witnessed the incident or who has information to contact Officer Blayne Matsui at (808) 961-2339 or via email Blayne.Matsui@HawaiiCounty.gov.
