CHP Searching For Freeway Overpass Brick Thrower In Deadly Concord Accident

CONCORD (CBS SF) -- The California Highway Patrol sought the public's help Monday for leads in the death of a 63-year-old grandmother who was killed when a brick, intentionally tossed from a freeway overpass, crashed through the window of her grandson's car as it traveled on Highway 242.

The incident took place at around 9:30 p.m. Friday on the interchange between Highway 4 and Highway 242. If you were on the freeway at that time and saw anything, the CHP asks that you call them at (925) 646-4980.

The coroner's office identified the woman Monday as Margarita Erostico Ruiz of Antioch.

A CHP officer at the scene late Friday night told KPIX the brick was thrown off an overpass. He said a wrench has been thrown from an overpass in the same stretch of highway only about 3 weeks ago. Authorities do not know if the two incidents were related, but were investigating it as a possibility.
