from the article: "Anchorage Police Department spokesperson Renee Oistad said in a subsequent email that detectives found Hall "through their investigative efforts," but refused to provide additional details."

Wow, it seems we are not supposed to know anything about police activity beyond what APD chooses to share with us.  APD, public servants? I don't think so - not any more - APD is telling us what to do and think. As citizens we are no longer entitled to information from the police (or other justice related government entities) supposedly for our own good. Get used to this I suspect. It will be "their way" or the highway for a while.  I think some heavy handed push back is in order if we really expect to retain our freedom.
