I discounted that. She could have easily reached that glass. Look at the video
@sam_gordon posted you can see the lower fixed wall of windows were easily accessible to her. I think it wasn't easily accessible to
him because of the railing -- a warning as well as the 18" gap that there could be a potential open window above.
He was reaching for an excuse. I truly think he believes it, his brain is compensating for his horrendous actions. However, the video proves otherwise. Once you see it you know his story isn't accurate. He has to accept responsibility.
