Tune in to FOX News Channel this Saturday at 10 p.m. and 1 a.m. and Sunday from 10 p.m. to 12 a.m., 1 a.m. ET as award-winning and veteran journalist Geraldo Rivera brings you two special broadcasts this weekend!

Saturday, August 20

Tonight, FOX News presents "The Pizza Bomber Mystery." It was a crime that shocked the nation — a 46-year old pizza deliveryman, armed with a homemade shotgun and crude bomb, robs a bank in Erie, Pennsylvania.

He is quickly apprehended, but this is only where the story begins. As he sits handcuffed on the ground, he claims the bomb was locked to his neck by an unknown assailant who forced him to rob the bank and follow a macabre "treasure hunt" in a desperate attempt to stay alive. But before the bomb squad can arrive to defuse the device, it goes off, killing him instantly. In the next four weeks, two more people linked to the case would die — one body is discovered hidden in a freezer, the other expires in bed.

Now Geraldo brings new, never-before-seen information to light, including a video confession and an eyewitness the FBI had previously overlooked. It's a story everyone remembers but few really know.
