Watching "Motives and Murders" tonight on Id, a case of a woman murdered in her home by a man pretending to want to buy her house, LE was very clear that they were able to obtain his movements via records showing which towers hit at specific times. I know there was a lot of discussion about whether or not this was possible and clearly, it is. The perp was placed in the neighborhood of the murder victim.
I know towers are far more infrequent near MR's house but hope they have tracked his movements as closely as possible for Sunday night and all day Monday.
I am so discouraged with the lack of movement in Dylan's case. i fear that if MR is truly not involved, the perp has got away clean. I cannot think of too many cases solved much later, except for those when LE had a suspect early on but was just awaiting an opportunity to bring charges. Not many when there was no apparent suspect over several months, as far as I can recall, were later solved. I know there have been cases solved decades later, but it is almost always someone they always "knew" had done it.
Also the idea of MR "hiding" Dylan, which never worked for me on any level, has gone beyond reasonable at this point. For me, we are and always have been at, back to a stranger/unsuspected neighbor, or MR. If not MR, someone got Dylan to leave the house with the lure of a ride to R's house. But I have great doubts about that, as I do not believe in the necessary coincidence of his phone giving up the ghost at exactly the wrong time.
