I think it was something along the lines of what one of the analysts was saying on TV before...She wasnt watching the kid, she drowned in the pool, mom freaked, hid the body and ducked her family for a month. The made up people, and job, story, because she is a nut job. Possibly not to wanting the police to dig into her family past because theyre all screwed up too...Either way she's a bad mother who didnt deserve to have a kid, and deserves to pay for her negligence.
