Investigations of the 1993 World Trade Center Bombing

 
Eventhough the cause of the explosion was not originaly known and with some people suspecting that a main transformer had blown, agents as well as bomb technicians from the ATF, FBI (Federal Bureau of Investigation) and the NYPD (New York City Police Department) all quickly responded to the scene of the explosion. Days after the explosion investigators started serveying the damage and looking for clues about what happened and who did it. A bomb technician found some internal component fragments from the vechicle that had delivered the 590kg (1,310-pound) bomb while combing through the public car park underneath the World Trade center, investigators also found a vechicle identification number (VIN) which was found on a piece of axle from the van, this was the crucial infomation that led them to a Ryder truck rental outlet in Jersey City. It was determind that the vechicle had been rented by Mohammad Salameh who was one of Ramzi Yousef's co-conspirators. The vechicle was reported stolen by Salameh who then returned on the 4th of March 1993 to get his deposit back, this was when he was arrested by the authorities. His arrest led police to the apartment of Abdul Rahman Yasin in Jersey City, New Jersey which Yasin was sharing with his mother, his apartment was in the same building as Ramzi Yousef's. Later Yasin was taken by the FBI to their Newark field office in Newark, New Jersey, he was then released. He flew back to Iraq, via Amman, Jordan. later on Yasin was indicated for the attack and in 2001 he was placed on the initial list of the FBI most wanted terrorists, he still remains on this list even in 2012.It was because of the capture of Salameh and Yasin that authorities found Ramzi Yousefs apartment in which they found bomb-making materials and a business card from Mohammed Jamal Khalifa. Khalifa was arrested on the 14th of December 1994 and was then deported to Jordan by the INS on May 5, 1995. In 2002 it was made public that Yasin who was the only person involving the bombing of the World Trade Center in 1993 who had never been caught by U.S. authorites, was being held as a prisoner on the outskirts of Baghdad, Iraq , he had been there since 1994. After being interviewed by Journalest Leslie Stahl for a segment on the TV program 60 minutes on the 23rd of May 2002 Yasin was never heard from again.
