I'm going to put a new link up here as a possible match.
I'm leaning towards "no" but have a nagging doubt.
Patsy Delios Destelia Ridens Clark
http://www.doenetwork.org/cases/2879dfar.html
Location: Arkansas, traveled extensively around the area and neighboring states.
Demographics: Not much really. No rule in or out. Age 55 is on the high side of consistent with the UID.
Physical appearance: Auburn hair is also consistent with color photograph. Some facial similarity. UID appears to be much tauter and leaner in appearance than the missing person but this could be accounted for by six months' time lapse.
Circumstances: Patsy disappeared in unclear circumstances, seen getting into a cab by her ex (with whom she was apparently on friendly enough terms). She was known to travel to unknown locations. She typically continued to cash her Social Security checks and apparently did not do so. She also did not maintain contact with her family following her disappearance. This makes me think that she came to harm shortly after her disappearance, making the six month time lag sit uneasily with the circumstances of Patsy's disappearance.
Could someone else please take a look at it though and see what you think and whether it is worth submitting?
