The two men are plainly Shelley and Lovelady...
You base this 'conclusion' on the single, doctored image that is the subject of this thread. You have been asked to present a shred of any other evidence to support your 'conclusion' and have failed to do so.
It is physically impossible for the two men to be Shelley and Lovelady if they waited for Gloria, listened to her story, went across to the concrete spur dividing the two Elm Streets and then made their way along the Elm Street extension where they were supposedly filmed.
It's physically impossible.
It must be noted that the subject of this thread can be summed up by this question - how could the washed out, inferior Sprague image contain such a wealth of amazing detail on 'Lovelady's' shirt?
The answer is...it can't.
Far superior images, containing far more information, show none of this detail or the famous bald spot. This is proof the Sprague image has been faked to give the impression it is Lovelady walking along the extension.
This faked image, and this alone, is the source of Brian's identification.
