From my understanding, they went to the cops multiple times. (The sisters, and Shari)Too little, too late. All these family members knew exactly what was happening in that house. They knew the children were treated abominably. Even the oldest daughter, who I will give a pass to because she is traumatized) knew what was going on. Why didn't they go to the cops? Why didn't they take some of the younger ones out of that environment.
The oldest ones left and left their young, vulnerable siblings there to bear the brunt of the assaults and probably bore the anger the mother felt at the older ones who left.
As for the father, why on earth would he take the oldest boy yet not fight to get the smaller kids out of there? Apathy is as bad as involvement. It boggles my mind that now that the cops are well aware of the treatment those kids endured, they are all singing like canaries. I don't think her sisters or her husband get a pass. Disgraceful.
