Regardless, it is a tragedy and everything should be done to identify women who are suffering from this condition, provide effective treatment, and prevent similar tragedies.
i think it is odd that a) a family member called to voice concerns, and Mom still was alone with the kids and b) that Dad echoed the concerns of the caller but allowed mom to be alone with the kids.
2 people noticed she Maybe could harm the kids but did not watch her like a hawk, as i would have.
Oh well maybe they are very young people.
