Two people were shot dead while sitting in a car in San Francisco’s Bayview/Silver Terrace area on the night of June 13, 2012. Police found 20-year-old Chastity Dollison in the driver’s seat with multiple gunshot wounds and her father, 39-year-old Allen Vance, in the front passenger seat with a fatal head wound. Dollison was pronounced dead at 10:33 p.m.; Vance died at San Francisco General Hospital at 2:07 a.m. the following day.

A third occupant, a man who had been in the backseat, survived with a leg wound and said he ducked when the shooting began; he did not get a good look at the shooters. Officers were told the trio had run out of gas and were waiting for fuel when unknown suspect or suspects approached the car and opened fire. Authorities identified a person of interest among women reportedly involved in disputes with Dollison and requested DNA testing of evidence; no gun had been recovered and the suspects fled on foot.

Anyone with information about the killings is asked to come forward.
