I read this the other day and haven't even been able to respond. This is not only very sad but it was so unnecessary! I can only imagine the pain you must have felt when you discovered what happened. I don't think words can ever explain just how upsetting I find this. I'm so so sorry.
I would like to say that you are doing a wonderful thing by trying to prevent this from happening to anyone else. There are so many things that happen in this world that we don't understand but there is always a reason. The needless loss of Kuhio is very tragic but you have turned a horrible thing into a mission of prevention. You may never know just how many others you save by doing this.
Look down with pride Kuhio because your family may save many so that your death was not in vain.
GodSpeed precious Kuhio!
