UPDATE: More Details on Fatal Sonoma Motorcycle Collision

The Sonoma County coroner's office this morning identified the motorcyclist who was killed in a three-vehicle crash Thursday evening as 43-year-old Sonoma resident Heath Kingsley Hunter.

Hunter was pronounced dead at the scene.

A passenger on Hunter's 2004 Harley Davidson motorcycle, Angelica Saragosa, 34, of Sonoma, suffered major injuries in the crash and was taken to Queen of the Valley Medical Center in Napa, then transferred to Santa Rosa Memorial Hospital. She was in critical condition this morning, a hospital spokeswoman said.

Hunter and Saragosa were riding south on Arnold Drive just south of Avenida Sebastiani in unincorporated Sonoma County near Sonoma around 8 p.m. when they approached a 1999 Dodge at an unknown speed, according to the California Highway Patrol.

The motorcycle collided with the rear of the Dodge and slid underneath a northbound 2003 Nissan, CHP officials said.

Saragosa was ejected from the rear of the motorcycle, struck the hood and windshield of the Nissan and landed 40 feet away in a dirt and grass drainage ditch on the east edge of Arnold Drive, according to the CHP.

The driver of the Nissan, who was not injured, remained at the scene and cooperated with the investigation, the CHP said. She was identified by the Press Democrat as 43-year-old Christine E. Luckin of Kenwood.

The driver of the Dodge, also identified by the Press Democrat as 47-year-old Fernando P. Castro of Sonoma, suffered minor injuries in the incident.
