This is the gun that killed President Lincoln.
I always thought that John Wilkes Booth was the only person involved in the assassination, but my visit to the Ford Theater in Washington D.C. changed my mind.
Booth was part of a larger conspiracy to kill the President. Other cabinet members were also targeted.
Many people were tried and hanged as a result of this conspiracy, including the first woman to be tried and convicted by a U.S. military court.
