What causes someone to become a serial killer? And can such a person be rehabilitated? This week, CBS News 48 Hours takes a look at the gripping story of a cold-blooded serial killer about to go free after only 20 years in prison - and the victims who want desperately to keep him in jail. Donald Miller was the quintessential boy-next-door. Growing up in a quiet middle class neighborhood in East Lansing, Michigan, Don seemed completely normal. Although he grew up in the mid-70s, when many of his classmates were growing their hair long and dabbling in drugs, Don was a clean-cut straight arrow. He served as a youth minister at his church. He went to the local college, Michigan State University, where he played trombone in the school marching band. He dated a girl who went to his church, Martha Sue Young. But Don Miller wasn't the normal boy-next-door. He became a serial killer.
