A Southern California man suspected of killing his estranged wife and abducting their 15-year-old daughter had been living with the teenager in his pick-up truck and hotels for weeks before the violence, authorities said.

Anthony John Graziano and his daughter, Savannah Graziano, were killed on Tuesday in a shootout with police on a motorway in the high desert east of Los Angeles after a 45-mile chase.
