Is the 3rd or 4th floor haunted, and who was kiled and where? I've heard that a boy died in the elevator...

Yes it is haunted you can sometime hear the screaming of the boys when you are in the elevator

A 15 year old boy and his friend got stuck in the elevator before it was a Walmart. When they crawled out of the roof of the elevator, it turned back on and crushed them. Those two now haunt the store

I read a woman died in the elevator and yes it reads its haunted.
