Ira Samuel Einhorn known as "the Unicorn Killer", is an American man convicted of the murder of his ex-girlfriend Holly Maddux. On September 9, 1977, Maddux disappeared following a trip to the apartment that she and Einhorn had shared in Philadelphia to collect her things. Eighteen months later, police found Maddux's partially mummified body in a trunk in his closet. It had been packed with Styrofoam, air fresheners and newspapers.

After his arrest, Einhorn fled the country and spent 23 years in Europe before being extradited to the US. He took the stand in his own defense, claiming his ex-girlfriend had been killed by CIA agents who framed him for the crime because he knew too much about the agency's paranormal military research. He was convicted and is currently serving a life sentence.

His moniker, "the Unicorn," came from his name, Einhorn — unicorn in German.
