Teen hurt in shootout charged with West Oakland mom’s death  A 16-year-old boy who was injured in the West Oakland shootout that left a mother dead from a stray bullet has been charged as an adult with killing her, becoming the sixth suspect implicated in the slaying, authorities said Thursday.  Julian Ambrose, who turns 17 next month, was cleared for release from Highland Hospital in Oakland and arrested Tuesday for allegedly being one of several people who fired guns during the March 9 gunbattle that killed 30-year-old Chyemil Pierce.  Pierce, a Kaiser Permanente human resources employee, was half a block away near her home when she was struck in the back of the head after she yelled at her children to run to safety.  Investigators said the violence erupted from a confrontation between two groups north of where Pierce parked her car after picking up her 7-year-old son and 9-year-old daughter from school.
