Bay Point ambush shooting turns to homicide after teen dies

A teenager who was shot last week in the Contra Costa County town of Bay Point died Friday after an intensive effort failed to save his life, prompting sheriff’s investigators to begin a full-scale murder investigation.

Harley Crawford, 18, of Bay Point and Oakley was pronounced dead at a local hospital, six days after he was apparently ambushed and shot while sitting in a vehicle, according to the Contra Costa County Sheriff’s Department.

Investigators found Crawford in a vehicle, suffering from a gunshot wound, at 10:57 p.m. last Sunday near Anchor and Riverside drives. Sheriff’s detectives canvassed the neighborhood in search of a suspect, conducting interviews and working with other law enforcement agencies in the area, but so far nobody has been arrested.

The Sheriff’s Department is asking anyone with information about the shooting to call (925) 313-2600. Those who want to leave tips or leave an anonymous message can e-mail tips@so.cccounty.us or call (866) 846-3592.
