Woman killed on 405 Freeway

Investigators are working to determine why a Westminster woman walked into traffic on the 405 Freeway north of Magnolia Avenue, putting her in the path of a big-rig truck that struck and killed her.

The woman stopped her car on the southbound shoulder of the freeway and walked into traffic Saturday, according to the California Highway Patrol. The truck, which was going about 55 mph, hit her from behind, authorities said.

The trucker tried to swerve out of the way, but his right wheel struck her. She was pronounced dead at the scene.

Authorities did not know if the woman intentionally or accidentally walked into traffic.
