We now have confirmation that our son’s friend, who recently went missing, is safe and sound. It has been reported that he, with another friend, planned to run away to Colorado. Fortunately for a couple of intervening parents, not related to the boys, they were persuaded to stay with them for a few days until they sorted their plans out. This apparently gave the parents enough time to contact both families and coordinate their reunion.
Thanks for all the comments, thoughts, and prayers. Both of these boys had a real set of guardian angels looking out for them.
