A  22-year-old California woman died Monday from injuries suffered when the pickup truck she was in ran off a road and dropped 50 feet into a Hilo rock quarry.

 Christina L. Delgado of Santa Cruz, Calif., was a passenger in blue 1992 Toyota pickup truck driven by her brother, a 26 year-old Keaau man on Sunday. The truck was traveling south on the Rubbish Dump Road when the Keeau man lost control. The truck ran off the left side of the road and dropped about 50 feet down at the Hilo landfill at about 1:35 p.m.

The truck landed on its roof and pinned Delgado inside.

Her brother was able to free himself from the vehicle and go for help.

Fire Department personnel extricated the woman from the vehicle and took her to Hilo Medical Center. She was later flown to the Queen’s Medical Center, where she died at 7:45 p.m. Monday.

The driver of the vehicle was arrested on suspicion of operating a vehicle under the influence of an intoxicant, negligent injury and having no insurance. He was released pending further investigation and is hospitalized at Hilo Medical Center.

Big Island traffic enforcement unit officers have reclassified the negligent injury case to a negligent homicide investigation. An autopsy has been ordered to determine the exact cause of death.

Police ask that any witnesses who saw the vehicle at the Hilo Drag Strip prior to the crash  should call police officer Andres Fojas at 961-8889.

Because this crash occurred on a private road, the death is not counted toward the island’s traffic fatality count.
