The woman killed in a head-on collision Thursday in Hau'ula has been identified as Vicki Norman, according to the Honolulu Medical Examiner's office.

The 57-year-old Hau'ula resident was driving a silver Chrysler van south on Kamehameha Highway when a Marine troop transport truck veered into her lane, police said.

The collision pinned the woman in her vehicle, police said, and she died at the scene.

The seven-ton Marine truck, with two Marines inside, was on its way to Marine Corps Base Hawai'i from the Kahuku Training Area.

The 19-year-old driver and 20-year-old passenger were uninjured but were taken to Tripler Army Medical Center for evaluation. The Marines and the truck are with the 3rd Battalion, 3rd Marine Regiment based at Kane'ohe Bay.

The accident happened shortly before 2:30 p.m. in the vicinity of 53-729 Kamehameha Highway near Puhuli Street, police said.

The medical examiner said the woman died of multiple blunt force injuries due to a motor vehicle collision.
