Carl Panzram - Labeled by some as the most sadistic serial killer in modern times, Panzram claimed twenty-two murders and over 1000 rapes of young men. He is most famous for robbing the house of President William Howard Taft, stealing jewelry and bonds and a Colt M1911 .45 caliber pistol. He bought a yacht with theft at Taft's home and would lure drunken sailors from New York City bars there, where he would sexual assault and kill them. He committed crimes all over the United States and was finally executed in Leavenworth in 1930.
