His fear is that the Stockton serial killer has targeted people who are alone, often sleeping in tents or cars. And most of the victims are Latino. Herron, who identifies as Hispanic, says that adds to his concerns.
"Best thing I could say is if you go out, go to work in the morning, go with somebody or start carpooling. Because if he is going to be out there killing people, until he gets caught, everybody is at risk," says Herron.
Stockton police say ballistics tests link the serial killer to seven shootings. Six were fatal, including a man in Oakland. Five of the shootings happened since July 8.
Officials says all the victims were ambushed. None were robbed. And there is no evidence of drugs or gang violence.

She says she will be talking to family and friends to come up with a safety plan. As she puts it, she is even afraid to put the garbage out.

"Nothing good is happening after dark. If you have to be out, be with someone, be in a lighted area. We're all concerned about what's going on but all the time you need to be concerned about your surroundings," said Chief McFadden.
