I am not sure that the parents knew EO was at AB's. The 6 year old was in the woods when she wasn't supposed to be. Therefore, I don't know that the grandparents knew EO was there, and I don't know that EO's mom knew she was at AB's. The three girls may have met up in the woods themselves.
Now that was pure speculation. I have seen several people say that the grandparents didn't know EO was there. If that is true, EO's mom could have been in the same boat. EO's mom could have thought that she was in the woods, but knew nothing more.
That day was probably the only day that week it didn't rain here. It was actually very nice that day, which is why kids were playing out side. They had been couped up for the last several days.
I have read the EO was afraid of the woods. IF thats the case why would she be in the woods. It is my understanding that EO was over at AB's playing with the 6 yo outside the house.
