Ballistics tests have linked the fatal shootings of six men and the wounding of one woman in California — all potentially at the hands of a serial killer — in crimes going back more than a year, police said.
Authorities last week announced that five men in Stockton had been slain in recent months, ambushed and shot to death alone in the dark. Late Monday, police said two additional cases last year — a man's death in Oakland and the non-fatal shooting of a woman in Stockton — had been tied to those killings.
