A Cambodian immigrant shot and killed her son-in-law, two teenage granddaughters, and herself yesterday in Seattle's worst shooting incident in years. "My mom has gone crazy," a daughter who survived bullet wounds told police. No motive has been established. Family members say the 61-year-old matriarch was mentally ill. "Grandma just shot them for no reason," a family member who arrived at the home shortly after the shootings told the Seattle Times.
