In June 2004, a volunteer group of families and victims from the incident, "Families from Pan Am Flight 73", was formed to work toward a memorial for those killed in the incident, to seek the truth behind this terrorist attack, and to hold those responsible for it accountable. On April 5, 2006, the law firm of Crowell & Moring LLP, representing the surviving passengers, estates and family members of the hijacking victims, announced it was filing a civil suit in U.S. District Court for the District of Columbia seeking $10 billion in compensatory damages, plus unspecified punitive damages, from Libya, Muammar al-Gaddafi and the five convicted hijackers. The lawsuit alleged Libya provided the Abu Nidal Organization with material support and also ordered the attack as part of a Libyan-sponsored terrorist campaign against American, European and Israeli interests.
