Why couldn't he "collect" her?
Why didn't a five year old run with grandpa?
My guess is because she may have been sleeping. Soundly.
Other option is, she probably was trained how to act in case of such an occurance.

Now that the lunatics know that he had a "panic" room, they'll just bomb the place next time. I suggest he move.

“Armed with an ax and knife, the suspect entered the artist’s home shouting threats of “blood” and “revenge,” according to Westergaard, before he and his granddaughter, who was in the home on a sleepover, fled into a specifically created safe room and awaited police who arrived two minutes later.

I guess she won't be visiting Grandpa anymore.

I agree that he should move because he's just a sitting target.

She had a broken leg in a cast.
