I have always questioned TN's comment that she had sent GMS over to check on the children. I think that she called GMS to go over because something had happened to Haleigh, I suspect either injured or just gone, because TN herself was not near by and could not be there quickly. Why would she feel that the children would need to be checked on? Following the report of Haleigh's disappearance, she and GMS had all the confidence in the world in Misty's mothering abilities, so why the need to send someone over to check on the children. IMO, both TN and her mother were called way before the 911 call. I believe that Tn arrived so quickly with photo in hand because she was expecting the call and was only down the road at GMS home or even closer. JMO, of course. I think that she is now out of sight because she is the grieving grandmother and maybe she is angry at Ron for something he may have done. JMO.
