Just a thought:
There is a glaring omission in the affidavits of both Shelley and Lovelady - that they walk down to the railroad tracks and enter the TSBD through a door on the west side of the building. In their affidavits both men give the very distinct impression that they re-enter the TSBD through the front door.
Indeed!
And another thing-------------Mr Shelley's affidavit is all about him singular (I ran out across the street, I ran into Gloria Calvery, I went back to the building).
There appears to be no sign of Mr Shelley on the steps in Darnell, but a figure looking a lot like Mr Lovelady is in evidence there-------------
The effect of Mr Shelley's change of story appears to be to
a) keep him on the steps for a longer time
b) thereby keep Mr Lovelady and himself paired up
Is Mr Shelley helping Mr Lovelady out in some way? Or is he getting Mr Lovelady to help him out?
One thing is for sure: Mr Shelley's blatant relocation of his encounter with Ms Calvery (from out at the corner of the park to at the front steps) is most troubling. As is the bizarre time estimation
both men give for their sighting of Officer Baker and Mr Truly fixing to go inside the building
