The collision happened at shortly before 7 p.m. yesterday, about 415 feet east of Marconi Road, HPD said.

The city medical examiner's office has not yet identified the man who was killed. However, a family member today identified him as Kyle "Kapono" Newalo. He said Newalo had recently married and had a child.

According to police, a gray 2000 Toyota Tundra pickup truck driven by the Kan'eohe man collided with a four-door, silver 2008 Chrysler 300 driven by a 21-year-old North Shore woman.

Police said the pickup was traveling east-bound on the highway when it tried to overtake another vehicle. The pickup crossed the center lane into the west-bound lane of traffic, and continued onto the west-bound shoulder before veering back on the highway where it crashed head-on into the Chrysler.

Witness Mitch DeGeus of Kailua said he was driving from the North Shore toward Windward O'ahu when a pickup passed his vehicle, then another vehicle before colliding with the oncoming Chrysler.

Police said air bags were deployed in both vehicles. They said the driver of the pickup, who was not wearing a seat belt, suffered severe head injuries and was pronounced dead at the scene.

The woman, who was wearing a seat belt, was taken to The Queen's Medical Center in critical condition. She suffered "broken arms and legs" according to police. Her condition was later upgraded to serious, they said.

Police said speed was a factor in the collision, but it is not known at this time if drugs or alcohol were involved. Kamehameha Highway was closed in both directions at the scene during the initial investigation.
