Dal-Tex Building

Several conspiracy theories in the assassination of U.S. President John F. Kennedy allege that some of the shots fired at the President's motorcade originated from the Dal-Tex Building.[7] In September 1966, Triumph's Lawrence R. Brown published an article stating that the bullet trajectories were traced back to a second floor window in the Dal-Tex Building.[8] Jim Garrison told Playboy in September 1967 that the building was "in all probability" as being one of four locations in which snipers fired at Kennedy.[9] Garrison later claimed that there were four assassination teams, each consisting of a rifleman and a lookout, including one on the seventh floor of the building.[10] In November 1967, Josiah Thompson stated that his study allowed him to conclude that there were four shots from three different firing positions during the assassination. Thompson also concluded that the Dal-Tex Building was located in a zone also including the Dallas County Records Building and parts of the Dallas Criminal Courts Building that he determined could have been the location for the source of the second shot.[11] He said that a young man was arrested just minutes after the shooting, taken in for questioning by police, then disappeared in the confusion.[11]

In the May 1970 issue of Computers and Automation, Richard E. Sprague said that he used computer analysis of still photographs and movie films taken in Dealey Plaza.[12] Implicating four gunmen and at least 50 conspirators in Kennedy's assassination, he concluded that two shots had come from the Dal-Tex Building.[12] Five years later in September 1975, Sprague and L. Fletcher Prouty stated that their study of still photographs and film of the assassination revealed that the fourth floor of the Dal-Tex Building was one of three or four firing positions during the assassination.[13]
