With interviews from key witnesses, authors Dave Shampine and Daniel Boyer recount the grisly story of this New Year's Eve North Country nightmare, which is still shrouded in mystery today.

The names Peter, Barbara Ann and Gerald Egan were familiar to Watertown police before December 31, 1964. The police suspected the trio in a long string of burglaries, and they were under investigation by the FBI for grand theft auto. But on that New Year's night, the Egans were shot execution style at a rest stop off Interstate 81. The gruesome gangland-style killings puzzled local and state police. Theories ranged from a simple confrontation gone awry to a premeditated act of retribution by hardened criminals who feared the Egans would turn state's witness.
