That afternoon, police went to the home to check on the Chadwicks after neither parent had picked up their children from school, and officers found blood stains in a bathtub and signs of a struggle, authorities said.

Chadwick was picked up the next day in San Ysidro, near the Mexican border, and later led investigators to his wife's body in a dumpster in the San Diego suburb of Lakeside.
