A fifteen-year-old boy died from a mysterious gunshot wound to his head while he was sitting in the lobby of his father's gun club. Ballistics, laser technology, made-to-scale models, and the latest in forensic animation showed that bullet had followed a tragic course after a misfire at the outdoor range.

A woman disappeared and her husband became the prime suspect -- especially after police found a huge bloodstain on the carpet of their bedroom.

Forensic File, episode titled, "Without a Prayer", was created because of atheist, Madalyn Murray-O'Hair's activities in removing daily prayers, from public schools, in the early 1960's. There were three deaths, Madalyn, her second son, Jon Garth Murray, and Robin Murray-O'Hair. Robin was a daughter of Madalyn's Christian son, William J. Murray. All three were killed by a temporary atheistic member she fired, David Roland Waters. Madalyn fired Waters after he stole from the atheist headquarters.
