Congressman Daniel Sickles of New York murders Philip Barton Key in the street in Washington D.C.

Daniel Sickles shot and killed Philip Barton Key on a Sunday morning near Lafayette Park in Washington D.C. following his wife's confession the previous day of her protracted adultery with Key.   Key, the son of Francis Scott Key, nephew of Chief Justice Taney, and himself a U.S. District Attorney, had rented a house on 15th Street in the capitol for their assignations and it was near there that Sickles waited for him and shot him down.  (By John Osborne)
