I don't blame you. How frustrating. I’m pretty much convinced that this has to be Bayard Cousins, and whether it’s getting an organization such as
@othram involved and/or crowd-funding (I’m not even sure if there is a need for either), there HAS to be a way to determine whether this is Bayard or at least if a sample of good enough quality can be prepared for comparison purposes or not.
I know someone who, due to his severe OCD, only wears maroon tops. He has been doing this for almost 25 years (started around age 20). While this may not mean anything, the shirt Bayard is wearing in his NamUs photo does appear very similar to the one our John Doe was found in.
