Let me preface this by saying I am not convinced Kyrons parents are not involved, but I not convinced they are involved either.
I am not sure if it has been suggested, but another alternative to the Dads email and reactions of the family could be guidance from Kyrons step dad. He is part of LE not local.
I am sure he has a good understanding of missing person cases and has learned over the years what works best and what does not work best. He could be the one advising the family not to speak to the media. He could be suggesting a quiet united front.
Also, I just want to put out there a different view of the whole idea of what is a normal and whether or not SM and Dad are reacting normal. I lost my baby brother to cancer when we were both in our twenties. I didnt cry when I showed up at the hospital too late to say good bye. I didnt cry at calling hours when I was in the receiving line, and I didnt cry at the funeral. I am an introvert by nature and a very private person. My heart was broken, and I sobbed until I couldnt breathe in private, but not one tear did I shed in public. Additionally, at the calling hours and funeral I was too worried about my parents to be concerned about anything else. I know that people in our small community thought my reaction was inappropriate ect, ect. All I am saying is people process stress and grief differently. Additionally, if SM and Dad truly did not know where Kyron was it is unfair to expect, a few days later, for the email to account for what happened when they realized he wasnt on the bus to be completely accurate. Stress does strange things to your mind. Many years later I still distinctively remember my thought pattern at my brothers funeral, and I thought I was losing my mind. I was not thinking normal. I remember staring at his friends in the front row of the funeral home crying, and my mind couldnt process it. I went on auto pilot. If my child was missing, I am confident my mind would go on auto pilot. I would go into survival mode, and I can tell you that my survival mode would not appear normal to those witnessing it.
Again, I am not saying the parents are or are not involved, I just wanted to give everyone a different perspective/view on their behaviors.
