Several years ago, I ran a near-drowning call (we resuscitated the child fortunately making it a "near") on a roughly 28 month old child. The entire family was home and it was fall and it was cooling down, and the family was no longer using the pool, so the back doors were locked. The child removed the cover from a small pet-door in the back door, and climbed through sideways, as that's the only way the child could fit. The clothes were left between the door and the pool, where after a 7yo in the house didn't see the sibling anywhere and the family started scrambling to find the child. They did, face down in the deep end on the bottom with no clothes on.
It can happen so fast that no one even knows they are missing, same happens with toddlers opening front doors and they are found in a busy roadway blocks from their home, and when they are returned, the parents are stunned that the child wasn't "playing in the room" where they last saw them.
Why then, if this was such an accident, wouldn't anyone not call 911?? Who knows yet... we may never know, and that might turn out to not even be what really happened. An accident can be logically and legally explained away, a cover-up cannot. If this is in fact a cover-up, it's imperative to "pin the tail" on the correct donkey/donkey's... otherwise, justice isn't served. JMOO
