Joanna Jenkins (NamUs MP # 23572)

Joanna Jenkins went missing on November 1st, 1977 from Oak Hill, Ohio in Jackson County. Few details are available in her case. Her NamUs profile doesn't offer much and that will slow down any websleuths out there. However, anyone looking at this case should be aware that leads turned up in 2005, leads that were apparently ignored at the time and don't seem to be covered all that much online. Whether they have been looked at since is not a matter I know of:

From the Marysville Journal-Tribute (Nov 28, 2005):

The source above mentions that there is an informant. He claims that Jenkins was thrown down a well by a man that also struck her. Anyone working on this case could look for human remains discovered after November 1st in 1977 in such a location. NamUs says Jenkins' DNA is tested so any remains found in a well that has its DNA tested is not likely to be Jenkins as the computerized systems would link them without any help.
