Thank you for your suggestions and help. The Charley Project is a great reference but more are needed.
I am guessing there are families out there with missing loved ones, but because law enforcement back then did not take missing serious someone who went missing, "it is a family matter, they will return" was the usual law enforcement answer. They may not be any formal police report. But newspapers are.
So if anyone is scouring old newspapers for missing people from that time frame, give me a shout. "We" are interested
"The answers are out there... but who has 'em?"
