They Apparently cannot find this poor mans remains to exhume him and they do not think it is a priority to do so. If anyone finds out more on this please let us know. That is very sad and very wrong. I pray they are trying to find out where he is located. Someone must care what happened to him and is still looking for him.
I don't know that they've tried to located this man. I do know that he was not on the list of 7 who were (all but one) exhumed at the Dunks Ferry potter's field in August 2018. They had chosen younger unidentified. Mostly children - teens.
Those cases were:
Black female (the girl in the box), age 4-6, 5/3/1992. I'm fairly certain she is the one they were unable to locate.

"They had opened the Girl in the Box's grave first, and dug down to where they thought she rests, but had not found her. By day's end, they narrowed their search to a few yards of earth nearby. Come morning, they planned to search anew, determined to find a little girl, no longer forgotten."
