I just watched the statement/pc or whatever it was, and the one thing that struck me was, IIRC, BD said that as soon as DD called with the news that HD hadn't been at her friends, BD immediately said she was calling LE to file a missing persons report.
Why immediately? Given her, IMO, laid back ttitude toward HD's comings and goings, why did she immediately panic and decide that she was going to report HD missing to LE? HD had, according to news reports, lived with friends and her dad over the course of the past year...she's seemed to have had a nomadic life. Moreover, BD was, IMO, rather unconcerned about her daughter's whereabouts the night SA told her that HD had gone to spend the night with a friend that she'd never spent the night with before, ever. Sure, BD said that she was a bit upset that HD hadn't called to check in (why is it HD's responsibility to do this? Is she the parent???)...but otherwise, BD has said more than once that she was NOT WORRIED about HD. This despite the fact that 1) her daughter was staying at someone's house that she had never stayed at before, 2) her daughter had not asked for permission to stay with this friend she'd never stayed with before (and by all accounts, was not expected to ask for permission to spend the night outside of her own home), and 3) BD did not ever met the parents of the girl HD was staying with (did she even know where they lived???).
Given this EXTREMELY laid back attitude about her daughter's whereabouts, why on earth would she panic immediately upon hearing that, according to DD, HD hadn't been with her friend? Maybe DD had gotten the message wrong or was mistaken (he's a teenager texting another teenager, they are not the best communicators). Maybe SA had gotten the name of the friend wrong when he relayed the message to BD. Maybe HD had just stayed at her dad's house. Why the immediate...while she was still at work and with no phone calls to her ex or to HD's friends...thought to call LE about a missing person?
In many cases I've followed, parents of teenagers (and pre-teens) usually exhaust their immediate resources (i.e., they call of their childrens' friends, search the neighborhood, call the parent's of friends) before assuming the worst. Heck, in the recent missing mom's case in Missouri (or is it Michigan?), despite the fact that the husband was concerned enough after a missed 10 am phone call to come home and call his wife's parents...he did not call LE until later that afternoon (at his wife's parents suggestion) until after the kids came home on the bus...because it was only THEN that they knew something was wrong, because his wife would never not be there for the kids getting off the bus. IIRC, the family made phone calls asking if anyone had seen her during this time, but still...even though he was worried, he waited until it was absolutely clear that something was wrong before calling LE.
There was a tipping point.
And IMO, the phone call/text from DD to HD's friend wasn't enough to be a tipping point to push BD into panic/I must call police mode. NOT given her otherwise laid back approach to HD's comings and goings. I just don't understand why she didn't make other calls (or have DD make other calls) before hitting the panic button.
