According to Project Jason, Melvin Uphoff and Jacquelyn Rains-Kracman have been found safe. They both disappeared about a month apart from the same Nebraska town in 1965. They were both married to other people but seeing each other (although, to be fair, Jackie was separated and getting a divorce) and everyone assumed they had run off together, but no one really knew for sure.
Additional information about their location hasn’t been released and may never be. But I’m enthused that the two lovebirds have been located and their families finally know they are all right. First Everett Ruess and now this; it seems to be the week for ancient case resolves.
