110 - John List and America's Most Wanted

John List, a mass murderer that killed his entire family in 1971 was found 18 years later when he was featured on the TV show "America's Most Wanted", thanks in large part to an eerily accurate artist's depiction of what he would look like at age 60.  We discuss the case, how this was one of the first widely known effective uses of artistic aging,  and the class of killers known as family annihilators.
