I never did hear anything back about Faye Self as a potential match.
I freaked out when I saw Sheri Swims mentioned as a possible in another thread.
She has a "bubble like" scar on her upper left arm, which could be a vaccination scar, as is described on the upper left arm of the UID. She had given birth at least once, with the UID having given birth at least 2 times. The UID had a ceasarean, and I think a hysterectomy at the same time, no mention of that with Sheri. The UID is listed as 5'3 1/2 which is possible for Sheri at around 5'6". Sheri is listed as having blonde hair with possible red highlights. There are pictures where her hair is light brown also, and I don't know which was her natural hair color, but it seems she could have died her hair this color. Sheri had upper dentures and lower partials, could easily have had no teeth by 1998 if she was living a difficult or transient lifestyle. Sheri went missing from Florida. The UID was wearing a shirt from Florida. Also, I checked, and Florida does have some carbon black plants, so possibly she could have spent time working at a place like that. I think her features are very similar to the victim, including the eyebrows and strong jaw. The only thing I can't get past is that Sheri supposedly had her ears pierced and the UID did not. I do think even if the holes closed, you would still notice the piercings, no? This is what has stopped me from attempting to pursue this further. What do y'all think? Does that kill this possibility?
