Funny thing about that 1/8/64 letter from Day--he never mentions finding the bag. Hmmm... By then, the FBI had dragged out of Day and Fritz etc that Frazier had been shown the bag and had stated as fact that it was not the bag he saw in Oswald's possession. It seems that scared the DPD out of using it as evidence against Oswald, which would explain why they never got their stories straight. As far as they were concerned, it was like that stinking map--non-evidence. But the FBI and WC wouldn't let it go, and kept asking them about it, which resulted in the incredible mess we have today--with multiple men claiming they discovered the bag, or saw it discovered, and none of them telling a consistent or credible story about when and where it was found.
Day's final comment on the whole bag story makes the most sense about what happened that day. They found it but the detectives moved it before it was processed and the rest is just hoping the whole thing will go away. It is obvious they did not get together and fabricate a storyline. To their credit they did not try and stage the photo. Obviously they could not get their story straight about the discovery of the bag. Day's description of what it looked like in the corner when he first saw the bag is fairly descriptive.
Mr. DAY. I mean the pipe.
The sack was between the pipe and the wall at the top of the picture.
Mr. BELIN. That wall at the top of the picture would be the east wall, would it not?
Mr. DAY. Yes, sir; laying parallel to the south wall.
Mr. BELIN. Did the sack--was it folded over in any way or just lying flat, if you remember?
Mr. DAY.
It was folded over with the fold next to the pipe, to the best of my knowledge.
