of today's Lafayette Square, signaling Teresa with a handkerchief. Key continued walking, and Sickles sent an acquaintance outside to delay him. Sickles armed himself with several pistols, and intercepted Key at the corner of Madison Place N.W. and Pennsylvania Avenue, across the street from the White House. There, Sickles shot the unarmed Key twice, one shot directed at Key's groin. Key died about an hour later in a nearby house. Daniel Sickles was later acquitted of the murder in the first use of the insanity defense in the U.S. After the trial and death Despite pronouncements of forgiveness by both of the Sickles and a brief reconciliation, which caused an outraged public reaction against him, Sickles was effectively estranged from his wife after the trial. Sickles continued to serve in Congress. During the Civil War, he was commissioned as a Union general, receiving the Medal of Honor decades after he lost his lower right leg during the Battle of Gettysburg. Teresa took ill and died of tuberculosis in 1867 at about the age of thirty-one. Sickles later remarried a young Spanish woman whom he met while he was minister to Spain, and had two children with her.
