Proof that Prayer Person is not Oswald is NOT recent, Brian.
Everyone in the area concerned, known, unknown and disputed, have been known NOT to have been Oswald for the past 55 years.
I have no idea what proof you or Brian are referring to Duncan. Maybe I missed something and no one's bothered to point it out to me?
55 years has nothing to do with PM.
When he was first wondered about, apparently a few decades ago(by one only or two researchers/buffs and then forgotten) he wasn't much more than a dark figure in Wiegman, 2013 is when we saw him for the first time, like we can today in Darnell.
You know what went through the investigators minds when they first saw Altgens, "Is that Oswald?" they said, not "that can't be Oswald because he's our
victim suspect", for a time they actually considered it. I doubt they'd have made the same effort with PM though.
