I wish I were surprised about the salts (as reported on the video portion of the linked above WHCS report) but I cannot feign surprise. This mother is not only acting in an unusual fashion for one whose child is missing, she seems to have an attitude that it doesn't really matter what she does.
MOO is that she is very fatalistic, knowing she will be caught out for whatever her part is in whatever has happened with little Aliayah. I think she knows she is going to jail for a very long time and is therefore, simply living life as if she must enjoy every possible thing (including the illicit parts of her lifesytle) right now, before she is incarcerated.
MOO - this speaks (nay screams) volumes about who she is as a person and specifically as a parent.
