I wonder if this John Doe might be
Marcell Byers? Youngstown, OH which is about an hour away from Garfield Heights
Here is his
Websleuths forum.This is a sad case, even the FBI got involved at one point.
Youngstown Police are also looking for Marcell's relatives in order to enter his DNA in Namus and cross-reference it to the Ohio John Does. I believe they are looking to cross-reference it with this John Doe in particular.
Anyone with an ancestry account able to see into his lineage? Maybe a "Cynthia" is listed in his family tree somewhere?
