From what I've read, she was in an intensive outpatient program 5 days/week. Why she was in an IOP vs. inpatient has not been explained. It could have been anything from there were no beds anywhere to insurance said she didn't meet the criteria for inpatient.

As far as where was "Child Family Services," someone has to file a report of abuse or neglect for them to investigate and open a case. They aren't aware of every child in the state whose parent is seeking help for a mental health diagnosis. If she wasn't expressing that she was going to hurt her children in the program she was attending, there would have been nothing worthy of filing on. Plus there was a second parent who was home with the children most of the time as well. Reportedly he went out to pick up dinner on Tuesday night when this happened.
