Window should not have been open. I have to "think" anyone in their right mind would not have put a child anyone near that window if he knew there was no glass. I have to believe he did not realize there was no glass........how/why I don't know.......even if there was a glare/was wearing sunglasses,,,,,,,,,,,I would think you can see a difference between that particular opening and all the ones next to it, above it, below it..........only one open? this also seems odd to me.......how much ventilation could there have been with only one open? Can these windows be opened/(slides) by anyone?
Whatever happened..........stupid mistake.......slipped by accident........a child lost her life........tragic accident and can't even imagine living with it all.
