Lewis Powell, the would-be assassin of Secretary of State William H. Seward, was prone to goof-ups. You might even say he had the tendency to lose his head.
As you know from our previous post, Powell was one of the co-conspirators in the Lincoln assassination plot. After his bloody rampage in the Seward home, Powell was tried and hanged along with three other conspirators on July 7, 1865. That should have been the end of the story, but it took over one hundred years for Powell's tale to come to an end.
