It’s good you’re trying. At least someone is. But I can’t help but think how much easier it would be if you were playing around on that program using the input of the other 3 individuals that were in the company of the suspect that night. Better still if you had a world class sketch-artist in the room that could use the input of those individuals along with the existing face pics to produce a likeness much closer to what this guy actually looks like. The police could then release that image along with any other details that they have learned since the initial images were released. For example, a better approximation of his height which as you already mentioned would be easy to estimate in relation to surrounding objects in existing pictures. At the same time they could release video of the suspect walking (which they say they have) which may also trigger recognition by someone who knows him. At the bear minimum the release of these few items would get the story back in the media for a day or two. But as you already commented, it’s really hard to tell with this case what has significance vs what is negligence. They obviously know what they’re doing – they just caught a serial killer (even if it took a while – they got their man). I guess we just have to be patient. For all we know they already identified the guy and are just taking their time. Or of the thousands of tips that already came through Crime Stoppers maybe 2 or 3 names keep popping up and they’re confident they’re getting close. What else could explain the lack of perceived pro-activeness and sense of urgency?
