I have spent a few hours looking for a document that supports the story that Roscoe White spent part of November 22nd 1963 investigating a burglary. I could not find such a document (report or something like that), which does not mean it doesn't exist. His personnel file is online, although some of the scans are real bad, hardly legible.
I think Ricky White's story, that his father was an assassin for a US intelligence agency with the codename 'Mandarin' who shot the President and killed officer Tippit is a hoax. A money making scheme. Outrageous what people do to make a buck.
