All the deaths except for Irwin's were related to their job with NASA or the Air Force. Mike Adams and Robert Lawrence were not involved with the civilian space program. James Irwin already had several heart attacks before his death. All except two of the deaths happened at least one or two years before Apollo 11. Also, Brian Welch was speaking out against the moon hoax, so he would not have been a good target to be killed.
