It matters to us here, in that we try to sleuth with facts on this site. Does it ultimately matter whether BK wore glove at the grocery store, as was stated? Not at all. But the other claim, that the killer was stalking the victims for weeks before the murders, and that his cell phone pings showed that he was where the girls were very often, well, that matters. If that is not true, and at best it is unsubstantiated rumor, and people here do not know it is that, then it just muddies the waters and eventually becomes "fact" for many posters. I know nothing about the person who made the post on social media, that got picked up by the DM and NYPost, which are accepted sites, but I would be very doubtful that a local cop that surveilled the perp for a couple days, would be privy to those kind of facts of the case, and if he was, I would hope that he would be respectful enough of his profession, that he would not go blabbing such details to "friends". I will continue to file those claims away as rumor, at least unless and until I hear them from a named source. JMO
