Ira Samuel Einhorn (May 15, 1940 – April 3, 2020), known as "The Unicorn Killer", was an American environmental activist and murderer. His moniker, "the Unicorn", was derived from his surname; Einhorn means "unicorn" in German. As an environmental activist, Einhorn was a speaker at the first Earth Day event in Philadelphia in 1970. On September 9, 1977, Einhorn's ex-girlfriend Holly Maddux disappeared following a trip to collect her belongings from the apartment she and Einhorn had shared in Philadelphia, Pennsylvania. Eighteen months later, police found her partially decomposed body in a trunk in Einhorn's closet. After his arrest and release on bail, Einhorn fled the country and spent 18 years in Europe before being extradited to the United States in 2001. He took the stand in his own defense, claiming his ex-girlfriend had been killed by CIA agents who had framed him for the crime because he knew too much about the agency's paranormal military research. He was convicted of murdering Holly Maddux and served a life sentence until his death in prison on April 3, 2020.
