I feel like one could have been home with them or had them in one of the vehicles asleep possibly.
I agree with you CO. IMO, if the W4 had someone watching the children, they wouldn't have entrusted them to just anyone on such an important night and, yes, it probably would have been one of the grandmothers. But, I would think anyone babysitting would have been charged as an accomplice, and that has never happened. DeWine has stated that everyone involved with these crimes has been charged.
"DeWine lamented the ways in which the eight victims were “brutally and viciously” executed. No other suspects are connected to the case, he said..."
