I don't like it either, city, but my observation is that LE isn't showing their hand. They're purposely throwing everyone off so as not to compromise the integrity of their investigation. It fits with what Dane said, "police told me not to talk to the media". He probably felt too much pressure and made his own decision to make a statement or two. JMO
I'd buy that more if LE didn't make a statement about it. LE themselves have purposely have not said much, it makes no sense they would volunteer that they want to speak to this person and also make it a point that he/she is not a suspect. Why lie to the media if you haven't been talking to the media much to begin with?
As I said, the only way that makes sense is if Dane is not the new witness LE is referring to.
