Armando F. Peters, a former Wahiawa resident, turned himself in to police Monday at the main station for booking at 12:50 p.m. and was released on $50,000 bail.

First-degree negligent homicide involves driving under the influence of drugs or alcohol.

Peters was the alleged driver of a speeding 1998 Honda Accord that rear-ended a 1998 Dodge Dakota pickup truck on June 16, 2005, on Kamehameha Highway, a quarter-mile north of Leilehua Golf Course Road, at 10:40 p.m., killing the pickup's driver, Army Sgt. Ethan Ranz, 23, of Fertile, Minn.

Ranz, who had just returned to Hawai'i from combat duty in Afghanistan, was five days away from service discharge after a five-year hitch when he died at Wahiawa General Hospital an hour after the collision. He served in Afghanistan with the 2nd Battalion, 5th Infantry Regiment, and earned a Bronze Star.

Ranz had stopped the pickup in the far left northbound lane when it was struck by the Accord. The impact forced the truck across the grass median, into the southbound lanes and caused it to flip over, police said. Peters' car also crossed the south-bound lanes and crashed into a fence near Wheeler Army Air Field.

Peters suffered serious head and hand injuries, police said.
