Madalyn Murray O' Hair was a controversial "celebrity" throughout the 1960s, 70s, and 80s. She was the founder of the American Atheists Organization, responsible for getting mandatory prayer removed from schools, and deemed "The Most Hated Woman in America". On August 27, 1995, her and her granddaughter, Robin Murray, and son, Jon Garth Murray suddenly vanished, a note found on their office stating: "The Murray O’ Hair family has been called out of town on an emergency basis. We do not know how long we will be gone at the time of writing this memo.” Many thought the family had fled the country, since they were severely hated, but some knew better and feared foul play. The police in Texas sensed no foul play and refused to take on the case, but a reporter, John MacCormick did not give up and soon, everything was brought to the surface.
