5. The envelope contained several photocopied pages that had been reduced in size.
6. One page listed 13 chapter titles for the BTK story, showing that the material was arranged like a book or manuscript.
7. Chapter 8, titled "M.O.I.D. Ruse," had been blacked out, which is one of the most specific details in the packet.
