Me too, both of your posts did as a matter of fact. My own story is similar to s_finch. We lost our son to the world of autism when he was around two. It was very painful to lose the dream of a typical little boy. Then as he grew and became a Houdini, we learned even more how painful it was.
One day when our son was 4 he did disappear. He was inside with me while I was fixing dinner, my husband was right outside the door push mowing the front lawn. My son wanted to go out and swing on the play set, so I motioned to my husband that he was outside...my husband nodded and acknowledged him being there. One minute I looked out the window and he was swinging, and less than five minutes later he was gone. I hollered at my husband and asked where he was...my husband thought he had come back inside. We frantically searched for about 10 minutes. My son, because of his autism, was almost totally non-verbal at that age, so calling his name didn't help, he would not answer back.
I called the neighbors for help. I'll never forget my exact words. "Andrew had wandered off, please come and help us find him". Within minutes the fire department, and tons of neighbors where at the house searching. We finally found him about an hour later, over a mile away, near a small river that runs near here. He was safe, and happy. What a relief.
Never in a million years did we think he had been abducted, I knew he liked water, so my biggest fear is that he would drown, or fall into a ravine, or get hit by a car. That is what ran through my mind. Also, it took me several years after his diagnosis before I could start any type of autism awareness. It took a long time to deal through our own depression and grief. It wasnt until much later that we found Holland was a wonderfully unique place to be!
The McCanns behavior is quite odd. If Maddie was known to wander off, the first words from Kate's mouth should have been something to reflect that. "She's gone", "She took off again", or even "The little $h*t ran off", anything but her rehearsed kidnap rant.
What a horrific scare you had when he wandered off. I'm so glad you found him and he was/is o.k. My son is in class with several students with autism, and they are truly special just as I'm sure your son is.
