Traffic accidents over the weekend around the state claimed three lives and injured 12 people.

One deadly accident occurred near Wahiawa, another near Pearl Harbor and a third on Lana'i.

The city medical examiner's office yesterday said a 25-year-old Wahiawa woman died Saturday in a four-car, chain-reaction crash near Poamoho Camp, just north of Wahiawa. Three people were hurt in the accident.

Police said the Wahiawa woman was driving north on Kamehameha Highway near Nui Avenue in a 2003 Honda Civic when her car crossed the center line and collided with an oncoming Ford pickup truck driven by a 29-year-old Waipahu man.

The truck hit a southbound Dodge pickup truck carrying a man and two female passengers. They were taken to The Queen's Medical Center and treated for minor injuries, police said. A fourth motorist, a 19-year-old from Mililani driving south in a Honda, also collided with the woman's car but was not injured, police said.

The name of the dead woman was not released. Police said speed and alcohol may have been factors in the crash.

The medical examiner's office yesterday identified a motorcyclist killed in a crash early Saturday as Matthew Paycer, 23, of Schofield Barracks.

Paycer was traveling south on West Loch Road shortly after midnight when he lost control of his motorcycle on a curve and slid sideways into a concrete structure, police said.

Sixty-seven people have died in O'ahu traffic accidents so far this year, compared with 56 for the same period in 2004.

On Lana'i, Boyd Dean Walker, 26, was killed at 4:15 a.m. Saturday when his car went out of control and rolled over on a sharp right turn on Manele Highway, just north of Manele Service Road, police said. Three adult passengers were treated for minor injuries.

On the Big Island on Saturday, six people were injured, one critically, in a three-car accident on Hawai'i Belt Road near the 50-mile marker.
