John Frederick List was 15 when he was killed in a familicide at the family’s Westfield, New Jersey home on November 9, 1971. His father, John Emil List, methodically murdered John Frederick, his mother Helen, sister Patricia, brother Frederick, and his own mother Alma that day. The bodies of Helen and the children were placed on sleeping bags in the mansion’s ballroom, and John Frederick had returned home from a soccer game the same day before he was shot.

List delayed discovery by stopping mail and newspaper deliveries and telling the children’s schools the family was visiting a sick relative; the bodies were not found until December 7, 1971. He disappeared and lived under the name Robert Bob Clark for about 18 years, remarrying and moving to Colorado and Virginia. A 1989 America’s Most Wanted feature led to his identification and arrest on June 1, 1989; fingerprint evidence confirmed his identity. Extradited to New Jersey, he was convicted in 1990 of five counts of first-degree murder and given five consecutive life terms. He died in prison custody on March 21, 2008, from complications of pneumonia.
