The first collision happened in Kona. According to Hawaiʻi island police:

Responding to a 1:43 a.m. call, police determined that a Blue 2000 Saturn Vue SUV heading east (Mauka) had drove off of the right shoulder of the roadway. The vehicle then struck an aluminum light pole and rock wall. The 23-year-old female driver was transported to the Kona Community Hospital where she was later pronounced dead at 3:14 a.m.

The driver of the vehicle was not wearing her seatbelt at the time of the crash.

An autopsy has been ordered to determine the exact cause of death.
