As Marjan has noted, Romack could not be the man in the suit.
Who was it then?
Romack's account contradicts Adams' and Styles'. They have to be reconciled one way or another.
The fact that Romack did not see Adams and Styles does not mean they were not there. There is no contradiction.
Besides, why would Adams and Styles lie about where they left the building?
I am thinking that Barnett was indeed talking to Romack. There could not have been anyone else but Barnett & Romack in that area at less than 120 seconds.
No, Worrell was not in that area at that early time, but Worrell might have been the guy that Sam Pate saw running north many minutes after the shooting. And, that guy did not ever stop (& look back)(or see the killer exiting the dock & running south).
Romack we know had a white shirt & black pants. Strange, no-one wore black pants in 1963. Praps Romack was wearing a tie too.
He was a truck driver, but i think that he was the Office truck driver, & thusly might have dressed up a bit.
Anyhow, i think that Vickie Adams miss-remembered Romack as wearing a suite (no, he was just neatly dressed).
A few minutes later we did have Officers in suites (plain clothes) arriving at the dock (ie Deputy Sheriff Mooney & Co), but Adams was long gone by then.
Before Mooney we had Sam Pate (in a suite probly)(in his KBX radio van)(& his off-sider Dowdle), but that was 3 or 4 minutes after the shots (Adams was long gone).
The cop that stopped Adams (on the tracks NW of the TSBD) had to be Foster (who had been on duty on the TUP). Foster was imo the front runner (cop-wise) re taking sentry near the NW of the TSBD.
From that location Adams (& Styles) could have retraced her steps to the dock, but Adams decided to enter at the front of the TSBD, hence she continued to walk anticlockwise (South-West & then East) as this was the sensible short-cut to the front.
Shelley & Lovelady were near the grassy knoll carpark, & when they entered the TSBD (via the western ramp & door) Foster had (for some reason) already moved on (Foster ended up at the manhole on the south side of Elm St).
One problem is that Barnett never ever said that he talked to Romack.
Another problem is that Romack early on said that he had not talked to Barnett.
Barnett said that he did not leave the dock area until two plainclothes guys took sentry there. But that cant be true. Mooney & Co had to have taken many minutes to get to the dock. Praps Barnett was avoiding admitting that he had handed such a critical duty to a civilian.
And, after Mooney & Co (eventually) got to the dock (took sentry at the dock), Romack then relaxed his own sentry duty (but he did not return to his workplace for some time).
Barnett said that he passed the end of the TSBD by 20ft. But is that 20ft past the main building, or is it 20ft past the annexe.
Barnett said that he watched the cops searching the box-cars. But here he had to have been talking about the box-cars near the grassy knoll carpark, not the box cars near his dock.
To see the box-cars near the grassy knoll carpark Barnett had to have gone well past the box-cars parked near his dock. That would have placed Barnett much closer to Romack who was never very close to the TSBD.
But Adams said that Barnett was 2 yd from the kerb of Houston, but there was no such kerb near the tracks just north of the dock.
Still thinking.
