The apt manager was likely disgusted with the whole deal - not being able to ask for rent, and the slime parent taking full advantage of it by not even visiting her kids. Well, the courts are involved now. The kids will likely go into foster care. I hope they end up with someone who will take good care of them.
Yes, hopefully the surviving children will be placed in a good, safe home together. But the death of the 9yo... heartbreaking.
