Agree. When I watched the video it appeared that she was under the influence of something strong. Many have speculated that she was drugged. That's certainly a possibility but it's more likely that if she was in fact on something... it was voluntary. There's only a few things that I've ever seen that have caused a devoted mom to 'leave' her child. Heavy narcotics is unfortunately one. I know there's no evidence that she was a past user but following cases for years... it fits IMHO. I think that's why she was at the apartment (to make a purchase) and I think she is either out on a bender or ODed somewhere. Hope I'm wrong.
