Hawaii Island police report that a motorcyclist and his passenger died in a three-vehicle collision Saturday evening on Queen Kaʻahumanu Highway near the 94-mile marker.
The motorcyclist was identified as Rick Dupont, 47, of Kailua-Kona. His male passenger was identified Monday as Sean Henshaw, 47, of Ocean View.
Responding to a 7:32 p.m. call, police determined that a 2014 Nissan Altima, driven by a 23-year-old woman, was traveling south on the highway when her car crossed left of center and side-swiped a 2010 Ford Fusion heading north, then struck head-on with a 2013 Honda motorcycle, also heading north, which was operated by Dupont.
Dupont and Henshaw were thrown from the motorcycle upon impact.
Both were taken to Kona Community Hospital, where Dupont was pronounced dead at 11:55 p.m. and Henshaw was pronounced dead a minute later.
An autopsy conducted Monday determined that both men died of injuries sustained in the accident.
The operator of the Nissan, 23-year-old Rebecca Vetter of Honolulu, was taken to Kona Community Hospital for treatment and was later released. She was arrested on suspicion of first-degree negligent homicide. She was released pending further investigation.
The operator of the Ford, a 60-year-old Kamuela woman, refused treatment and was released by paramedics at the scene.
