I agree with you. It could look more that Maurice because he is older. I thought about that too. No, I do not know where you can find the detective magazine. I know I had a copy when it first came out, however, through many moves it has been lost. I know of one other copy someone had-an aunt of a friend. She sent her copy to "Unsolved Mysteries". When they contacted the eldest brother, John (I think) he did not want to do the story. Probably thought it was another prank or something, since now I read that the baby sister is interested in where the children went. Remember, this was in the early to mid 1990-s and caller ID were just getting started. So perhaps John thought it was a prank. I've been looking on E-bay, willing to pay what it's costs to purchase it, but I have been unable to find it. Remember, until recently you could buy detective magazines-they came out monthly. Some of the younger folks don't know that. I was hooked on detective magazines, still look for old ones at flea markets, etc. but can't seem to locate any old one except on ebay.
As for the man looking like the Sodders, he certainly does. Have tried to decode the message on the back-"Louis Sodder", "I love brother Frankie"
ilil boys, "A90132 or 35". Don't know what it means. Of course, a lot of people could look like the Sodders and it could have been an ugly prank. Only a expert would know for sure. I think I heard or read recently it was mail from Kentucky.
Fayette County Geneology Board has some postings-as well as Jonathan used to have a site. Don't know if Jonathan's site is still there. I put in Sodder family forum and found it a long time ago. Good luck!
