While it's no surprise that Lee Harvey Oswald's fingerprints were found on the 6th floor of the Texas School Book Depository on November 22, 1963. He worked in that building and primarily worked on the 6th floor daily stacking boxes of books. So, his fingerprints should have been there. But guess whose fingerprint was also found on the 6th floor the day of the assassination........ LBJ's hitman Mac Wallace! And just for the record...... he didn't work there!
