Is it possible some here agree - the vid itself appears to show DB abducting Cash, but person in vid -
- could be DB's twin, brother, or cousin? (speculating these ppl exist)
- could be a rando doppelganger? (w other known facts, darned unlikely)
I know you are saying that you doubt these possibilities are very likely, and you're just trying to imagine how some people may have come to the conclusion it's not DB in the video.
IMO, again I'd go with Occam's Razor. While there may perhaps possibly somehow somewhere be a doppelgänger of DB, the likelihood that this random doppelgänger showed up in a home where the actual DB has been, and was a friend of the son, is vanishingly infinitesimal.
Twin, brother or cousin? More plausible than a doppelgänger but extremely doubtful. I'm an identical twin, which is one of the reasons this case tears me apart. We do have the same DNA, but like all identical twins, we don't have the same fingerprints (which are caused by how we touch our mother's womb in utero). I imagine that DB left fingerprints on Cash, on the knife, on the doorknob, which would rule out any identical twin that exists. The neighbors would know if he has a twin, anyway. People from my childhood remember us because we are "the twins."
