Unmasked: My Life Solving America's Cold Cases

For a decade, the Golden State Killer stalked and murdered Californians in the dead of night, leaving entire communities afraid to turn out the lights. The sadistic predator disappeared in 1986, hiding in plain sight for the next thirty years in middle-class suburbia. In 1994, when cold case investigator Paul Holes came across the old file, he swore he would unmask the Golden State Killer and finally give these families some closure. Twenty-four years later, Holes fulfilled that promise, identifying a seventy-three-year-old former cop named Joseph J. DeAngelo.
