I can see how he was able slip away, little kids are fast....my DS(10) was like that when he was smaller. You could turn away for a second and he would be gone, lost in the crowd. It's terrifying when you can't find them. All kids are different, some wander, some don't. But being the parent of one wanderer and a child that did slip into a pool when we were right there, I can totally see how this could happen. I am sure that is what happened here, he slipped away, somehow got lost in the crowd and somehow ended up in the pool. Drowning is quiet, not like what you see in the movies. My oldest son (27) when he was small probably like 3 or 4, managed to slip into my godmothers pool and we were right there. He was playing on the steps and the third step was above his head and right under he went. Quiet, no splash, no scream - nothing. Thank goodness we were right there. Anyway, we continue to pray for Chase and his family.
