Yes, this. A complicated life with some history of legal and domestic issues and drama. And it is hard for anyone to imagine a mom killing her children but unfortunately it happens. LE sounds like they are being very thorough and hopefully in the near future there will be factual details including toxicology reports and prior events leading up to that day that will shed more light on the why.... Among the possibilities of catalysts for this tragedy, I have wondered if either of the girls had stated the desire to live with their father....not based on anything I've read, just a thought as to why she might have killed her girls, if indeed she did.
