On November 9, 1971, John List committed one of the most planned family murders in American history. The 46-year-old accountant and Sunday school teacher killed his wife Helen, his mother Alma, and his three children, Patricia, John Jr., and Frederick, in their 19-room house in Westfield, New Jersey.
List shot each family member with a handgun and put their bodies in the ballroom. He left a confession letter at the scene explaining what he did, then disappeared without leaving any clues.
