It's hearsay. Garner apparently overheard Belin taking about the two men "coming up" and could have innocently incorporated that into when she actually saw them, when they returned from the roof.
“Could have”. LOL.
The Shrould Letter just isn't that definitive; it has no times or specific places or a witness who saw Garner.
Compare that to the Oswald story, which has ZERO to substantiate it.
Adams would have her broke her neck trying to duplicate her fanciful madcap dash in three-inch heels.
It’s a constant source of amazement how omniscient Nutters think they are.
