McStay Family.......xx

Every time i watch i have new questions. Where are the McStay's? Why were the playhouses inside the house? Does the grandma think people were staying in the house? Drinks in bed rooms, etc Why does Joseph's friend (in real estate), answer NO to the question have u seen Joseph McStay? But has he seen Summer McStay? The fact that Joseph signed his name Bryan Joseph at the motel. Was he asking for help? The car has no signs of an intruder....did they drive it to the border? When they traveled in the past, did they keep in touch? Did their four year old go to school? What does a messy closet mean? In a rush? Laundry day? Nothing to wear? How bad was Joey's health and were they seeking treatment? Why wait ten days to call for help? Where are the McStay's? xx
