The Stockton Police Department is asking for your help.
The department issued a photo of the car that dropped off three armed men before Wednesday's deadly crime spree.
Two of the men were killed in a police pursuit and shootout with police. The surviving suspect has been identified as Jaime Ramos, 19.
The suspected robbers also took three hostages. Misty Holt-Singh was killed after one of the suspects used her as a human shield during the shootout with police.
The car appears to be a black, four-door sedan with tinted windows.
They are asking anyone with information to call 209-937-8377.
