Around five o'clock on Saturday evening, March 7, 1953, a TV repairman was at work in his basement workshop, unaware that he was about to step into a nightmare more terrifying than any late-night horror flick that he or his customers had ever viewed on their television screen.

When Paul Schultz went upstairs in his home in Nazareth, his wife, Claire, asked him to go out and look for their two children, who hadn't been seen since two o'clock. The search for the Schultz children didn't take very long at all; Paul found his children partially submerged in the shallow, ice-crusted stream behind their home.

This month marks the 73rd anniversary of the unsolved murder of Gail and Paul Schultz, Jr., who were slain just two hundred yards away from their home-- in broad daylight on a Saturday afternoon.
