It started with knickknacks being moved around the house. Then it was kitchen drawers being opened.
The haunting experience culminated when Rudy Calderon's family saw a Yiddish word scrawled on a bathroom wall with what appears to be charcoal.
The word, based on Google translate, means "danger."
Calderon, 28, thought someone in the Phoenix home was pranking the family with a series of paranormal stunts.
Now, he believes it's supernatural activity.
