RICHMOND, Calif. -- A Richmond woman was killed and a man was critically injured in a freeway shooting late Thursday night that closed westbound traffic on Interstate Highway 80 near the Richmond-Pinole border for more than four hours overnight, according to the California Highway Patrol.

According to officers on the scene, a shooting between two vehicles traveling westbound on I-80 took place at approximately 9:10 p.m. between Appian Way and Pinole Valley Road. The victim's vehicle drove another mile down the freeway before coming to a stop on the shoulder of the far left lane of I-80 just past the Richmond Parkway exit.

Authorities confirmed that Richmond resident Rhonda White was declared dead at the scene from injuries sustained in the shooting. The second victim was transported by CHP helicopter to John Muir Medical Center and is in critical condition.

California Highway Patrol spokesman Sam Morgan said that three other people were also inside the car but were not hit. They were being questioned by investigators about the incident.

Morgan said the shooting appeared to be a "random incident" and that investigators didn't have any indication it was gang-related.

Investigators were able to piece together a "sketchy description" of the shooter's car but had not identified any suspects.

For a time, a section of the freeway was shut down in both directions while Richmond police, Pinole police and the California Highway Patrol investigasted the shooting. I-80 was re-opened in both directions at 1:30 a.m.

Officers on the scene mentioned that this was the second shooting in the area of the freeway in the last three days following a non-fatal shooting that took place Tuesday evening. There was no word as to whether the shootings are related.
