One of the hijackers, Mohammed Ali Hammadi, was arrested two years later in Frankfurt, Germany. He was tried and convicted of Stethem's murder and sentenced to life in prison but was released in 2005 after serving 19 years. Three others, Imad Mugniyah, Hassan Izz-Al-Din, and Ali Atwa, were eventually indicted for their involvement in the incident. In 2002, they were added to the FBI Most Wanted Terrorists list. On February 13, 2008, Mugniyah was killed in an explosion in Damascus, Syria. On September 21, 2019, an unnamed hijacker was arrested while disembarking a cruise ship that had ported in Greece. His identity came up as being wanted by Germany during a passport check.
