I'm not surpised it isn't from that distance Alan but if you compare his profile pic which the FBI took of him wearing "the wrong shirt", the shape of the hair-"cut/style" itself is quite similar.
If Couch were just a photo, Barry, then maybe. But none of the frames--------including those showing him walking further ahead where we get more of a back view--------suggest what we know from the Martin film is a pretty darn glaring bald spot!
The frame in Couch that keeps being used has a white spot, but it's a film artefact! About as indicative as the 'bald spot' on 'Shelley' here
Also, if that is Shelley & Lovelady, their heights are all wrong! Lovelady should be the taller.
Also the woman I liked in the last portion of Darnell is big, with dark hair, in a black overcoat and she turns toward the TSBD at the last second.
This one?
