I agree it should be taken seriously. But let's not blind ourselves to the more unpleasant aspects of what may have happened.
No one is blind. We all know the possibities but we still have hope and we still need to know where she is. We are trying to get the word out so that if anyone saw the b/f, Louis Walls that night or Roxy that night, they will recall and notify LE.
Sorry if I was defensive about Roxy being a prositute, that was just the mother bear coming out in me. Of course, it would be better that she was a prostitute instead of dead but the point is...the perp is still out there and there are other potential victims. LE needs to solve this. For whatever reason Austin Police Dept has just let this slip away. Maybe the person of interest (b/f) is a "friend" of theirs. There is a huge amount of potential evidence that they just let go by..interviewing the b/f, and his ex-g/f, the motel room, the motel staff, the survalence videos, the person who had her ID, the car the ID was found in, investigating the 300+ cell phone calls after she was missing, etc..etc..etc. APD has done nothing but ignore this case. The spotlight needs to shine on this Louis Walls guy.
