With any three of these "theories", I think we would be able to complete the investigation if we were allowed "access". However, given the current lack of information (cell phone pings, GW's friends saying he was with them, GW being questioned, SK's bank records, SK's boss telling us is real job "duties and expectations", SK's boss telling us how much he had paid Steven over the course of their contract employment agreement, solid confirmation on when Steven went to Rubi..., SK's cell phone records, etc., etc.), I know it won't be. SOOO...that would lead me to the conclusion that someone on the "good" side of the law who has access to this information, doesn't really want this case solved or knows it will lead to an answer they dont want to accept. Even if LE was the one holding back information, I know they would have said by now that they have leads, but cannot release information at this time. Just saying...
Seems like pleading for more information, just falls on denial ears.
