Assassination
Bull concurrently worked on the Scud project, making calculations for the new nose-cone needed for the higher re-entry speeds and temperatures the missile would face. Over a period of a few months following, his apartment suffered several non-robbery break-ins, apparently as a threat or a warning, but he continued to work on the project. In March 1990 he was assassinated, allegedly by Iranian or Israeli intelligence services. One account states he was shot five times in the head and back at point blank range while approaching the door of his apartment in Brussels. Another account states he was shot by a three-man team on March 20, 1990, when he answered the doorbell.
The supergun project was stopped when its parts were seized by Customs in the United Kingdom in November 1990, and most of Bull's staff returned to Canada. The smaller test gun was later broken up after the Gulf War.
