IIRC, Mohammed, the DC Sniper, cheered on 9-11.
Ramzi Yousef was in Jersey City 1993.
A vehicle identification number (VIN), found on a piece from an axle, gave investigators crucial information that led them to a Ryder truck rental outlet in Jersey City. Investigators determined that the vehicle had been rented by Mohammed A. Salameh, one of Yousef’s co-conspirators.[22] Salameh had reported the van stolen, and when he returned on March 4, 1993, to get his deposit back, authorities arrested him.[23]
Salameh’s arrest led police to the apartment of Abdul Rahman Yasin in Jersey City, New Jersey, which Yasin was sharing with his mother, in the same building as Ramzi Yousef’s apartment.
