As you may remember things changed on Novemeber 24th. Oswald is killed by Ruby.
The next significant event that occurs for the Norman, Jarman and Williams occurs on the Monday the 25th when Carl Day visits the TSBD and enquires about the chicken lunch.
Mr. McCLOY. On the crime scene, that is, on the sixth floor, did you notice any chicken bones or chicken remnants of a chicken sandwich or lunch or the whereabouts, if you did see them?
Mr. DAY. Yes, sir; there was a sack of some chicken bones and a bottle brought into the identification bureau. I think I still have that sack and bottle down there. The chicken bones, I finally threw them away that laid around there. In my talking to the men who were working on that floor, November 25, they stated, one of them stated, he had eaten lunch over there. Mr. McCLOY. Someone other than Oswald?
Mr. DAY. Yes, sir; so I discarded it, or disconnected it with being with Oswald. Incidentally, Oswald's fingerprints were not on the bottle. I checked that.
Note that the other TSBD employees were not fingerprinted until June 1964 two months after Day testified to the WC.
