I've exhausted all avenues I can think of over the years. School forums, random amalgamations of words into Google, FB groups, even joined Ancestry and searched every girl born around 1966 that was called Kathy or a variant, there was thousands so it was just impossible.
DNA is the answer here I think, she's one of the most well known Does and yet nobody knows her
I've wondered what happened to Kathy from the motel photo. Unfortunately, I dont think Kathy is among the living. I have a feeling she was met with foul play within days or months after that photo was taken, and is dead somewhere and hasn't been found or is dead and is one of the Jane Does on this site. Sugarland prison is adjacent to Harris County. I think she looks similar to that Does sketch than Walkers.
