Kauai Driver Arrested for Negligent Homicide in Fatal Anahola Hit-and-Run

Five days after fleeing a chain-reaction crash on Kūhiō Highway that killed one woman and critically injured another, Thomas Castro, 47, of Anahola walked into the Kaua'i Police Department and turned himself in. He was arrested Wednesday, April 20, and charged with five counts: second-degree negligent homicide, first-degree negligent injury, second-degree negligent injury, collisions involving death or bodily injury, and inattention to driving.

The crash unfolded near state mile marker 15 on Good Friday, April 15, when Castro's southbound white Chevrolet pickup struck a truck that was making a turn in the roadway. That initial impact sent the second pickup careening into a northbound Ford MPVH. Castro's vehicle then continued onto the shoulder and struck a fourth vehicle before he left the scene, shutting down Kūhiō Highway during one of the year's busiest holiday travel days.

The driver and passenger of the Ford MPVH were both transported to Wilcox Hospital. The passenger, a woman, died the following day. The driver survived but suffered critical injuries. Kaua'i police have not publicly released the names of either victim.

The charges Castro faces carry serious exposure under Hawaii law. Second-degree negligent homicide is a class C felony, punishable by up to five years in prison and fines reaching $10,000. The first-degree negligent injury count is a class B felony, carrying a potential sentence of up to ten years. Together, the five counts reflect the compounding destruction a single driver's inattention caused on one of Kauai's most-traveled rural corridors.

Hawaii law prohibits any person from standing in the bed or load-carrying area of a pickup truck while the vehicle is moving, under HRS 291-14, and bars children 12 and under from riding in the bed under virtually all circumstances. The fines are modest, $25 per standing violation and $50 when a child is involved, but the physics are not: an unrestrained person in a truck bed has no protection in any collision, and ejection from a moving vehicle is among the leading causes of fatal crash injuries nationwide. On a two-lane highway like Kūhiō, where speeds, curves, and turning traffic all converge, that exposure is heightened.

Castro is presumed innocent until proven guilty.
