Patton Oswalt has credited his late wife, a true crime author, for the arrest of the notorious "Golden State Killer." Michelle McNamara wrote "I'll Be Gone in the Dark" about the man who authorities say killed 12 people, and raped at least 45 women in the 1970's and 80's. "The book really amped up all the interest in the case," Oswalt told NBC's Seth Meyers. The Sacramento County Sheriff arrested 72-year-old James Joseph DeAngelo Wednesday.
