In spite of extensive investigation by the Secret Service, the FBI, the Garrison office, the House Select Committee, and private researchers, no one has ever placed an Oswald “work area” on the second floor of the Newman Building, nor a “weapons storeroom” on the third floor. No one has placed Oswald at 544 Camp offices, with only one exception. Banister’s secretary Delphine Roberts did indeed claim that Oswald had an office there, but Roberts suffers from an extreme lack of credibility . She failed to come forward with her story until the late 70s, in spite of having been interviewed numerous times prior to that. Further, the building’s landlord, Sam Newman, the janitor and all the other tenants denied ever seeing Oswald there .
