As the sun rose over Washington, DC, on the morning of March 30, 1981, in room 312 of the Park Central Hotel on 705 18th Street NW, a guest lay in bed, anxious and wired after a mostly sleepless night. He had arrived the night before on a Greyhound bus, and like many other tourists who visit Washington from afar, he had a big day ahead. But unlike most of them, he didn't plan to see the Lincoln Memorial or the Capitol dome, or to peruse the exhibits at the Smithsonian Institution's various museums. No, this visitor had something different in mind. His name was John Warnock Hinckley, Jr., and he was going to try to kill the President of the United States.
