John Emil List slaughters his entire family in their Westfield, New Jersey, home and then disappears. Though police quickly identified List as the most likely suspect in the murders, it took 18 years for them to locate him and close the case.
John List was an outwardly normal and successful father. A Sunday school teacher and Boy Scout troop leader, List was a strict disciplinarian who insisted his children follow extremely rigid rules.
On November 9, seemingly out of the blue, List shot his mother Alma (above her left eye), his wife Helen (in the side of the head), and two older children in the back of their heads; he shot his youngest child, a son, several times in the chest and face. He then left the murder weapon alongside their carefully laid-out corpses. List had methodically devised a plan so that the bodies would not be discovered for quite a while, cancelling newspaper, milk, and mail delivery to his home in the days leading up to the murder. He then called the children's schools to say that the family was going to visit a sick relative out of town. By the time authorities discovered the bodies, List had vanished without a trace.
Local law enforcement officials had essentially given up looking for List when the television show America's Most Wanted began airing in the late 1980s. After a segment about the List murders aired on May 21, 1989, calls began flooding in. Although most of them proved to be unhelpful, one viewer claimed that John List was living in Virginia under the alias Robert Clark.
Indeed, List had assumed a false identity, relocated to the South, and remarried. In 1989, he was returned to New Jersey to face charges for the death of his family. The following year, he was convicted of five counts of murder and received five consecutive life sentences.
