Los Angeles police Sgt. Shannon Hale says the woman was shot in the head as a car drove by shortly before 5 p.m. on the 700 block of East 87th Street.
The shooting occurred in front of multiple family members while the woman was out in the front yard of the family home Wednesday.
Hale says the woman was visiting from Pomona and had no rap sheet or gang ties. She appeared to be an innocent bystander of possible gang activity.
Police do not have any suspect information.
