This might be relevant, but I always thought Debra looked a lot different in life than in her reconstructions/postmortem photos. Don't get me wrong; in terms of her facial features, the reconstructions are spot-on (even when compared to her childhood photos), but you can tell that she had been "living rough" in the period leading up to her death, even if she wasn't necessarily a transient.
Like I said in my last post on this thread, I'm really curious about this job at a real estate firm (?) that Debra had the same year that she was murdered. As I said before, she very well could have still held this job at the time of her death or close to her death. I wonder what the nature of her duties were at this job. If she had co-workers, maybe one of them heard Debra talking about people in her life who had been causing her problems.
Also, Debra might have been wearing those orange socks for a reason. Halloween was coming up. Maybe there was some sort of theme party or dress-up day at work. I guess some people try to spice up their outfits by wearing colorful ties/socks that go with the theme of an upcoming holiday.
I'm up in the air in regards to the relationship between Debra and her killer. When she was unidentified, I assumed that she had just been in the wrong place and the wrong time and had met the wrong person or people who ultimately took her life (i.e. via hitchhiking or sex work).
Now, though, I think that her life may have been slightly more stable than what I had initially thought. I think it's entirely possible that she wasn't hitchhiking at all. I also think it's likely that Debra had a permanent address at the time of her death (as in, something like an apartment or a house where she would have a room indefinitely). Even if Debra was not a transient, I'm not sure that Debra had the means to live alone. That means that wherever she was living, there were probably other people with whom she would have contact on a very regular basis, and they would have definitely noticed her absence.
