A Napa neighborhood is on edge after two young women were gunned down over the weekend. And one witness says they appear to be teenagers. Brandon Perez rushed to help a girl but she had already died. The other woman died at a hospital. Perez described the scene to KTVU Saturday night as three girls arguing on the side of a building when a car pulled up and someone opened fire. The girl he went to was shot in the head and back. The two others darted inside a house and one was hit in the stomach. Anyone with information is asked to call the police.
