when the local news channel reports (in part): Stockton police chief says ‘stop the killing’ as they investigate serial homicides; person of interest sought “By definition, you could probably very well call these a series of killings, but at this time we don’t know if it’s a person or two or three, we just don’t know,” McFadden said at a news conference on Friday. "We believe there is some interconnectivity." McFadden urged people to be careful when going out, especially at night. "I can't say enough, you need to be aware of your surroundings. Please do not fall victim. Be alert, have your head on a swivel, stay where it's lit," he said. He also advised people to go out in groups, communicate with others and stay in well-lit areas. The department has also increased patrols, with more resources working around the clock. The full news report is here: Yay... not so much.
