I just watched the "Disappeared" episode about Roxanne, and I have a few basic thoughts. For me there are three things that could have occurred: (i) Louis Walls killed her and somehow managed to hide her body very well in a very short period of time; (ii) Roxanne left the motel, walked down the street and eventually got into a taxi driven by Geoffrey Moore --- whom she had already ridden with --- and he assaulted her, killed her, hid her body somewhere and kept her driver's license; or (iii) Roxanne left the motel, walked down the street and was eventually assaulted by some bad person or persons in that bad neighborhood.
While there is good reason to regard the first scenario as the most likely --- Louis Walls was the last to see her, they got into an argument, he had a history of violence --- it is seriously undermined by the alibi witness, who claims she saw him follow Roxanne out from the motel, that she saw Roxanne walk down the street, and that she spent much of the rest of that night in his bed (!).
This is why I like the second scenario, the one involving Geoffrey Moore. As I mentioned, she had already ridden in his taxi earlier that day or the previous day. We also know that she didn't have money on her, so it's possible that he saw her walking down the street, asked her if she needed a ride and told her, when she said she didn't have any money, that that wasn't a problem. What happened after that is impossible to say, but women have been assaulted in cars and by taxi drivers many times. Another thing that makes Moore a decent suspect is that unlike Louis Walls, Moore had a car he could use to drive somewhere and dispose the body. He also didn't come under suspicion for several days, so he had time to hide evidence of his crime.
For the moment, I think that's the most likely scenario to pursue investigation of. Geoffrey Moore.
