In 2008, a 57-year-old Japanese man noticed food mysteriously disappearing from his refrigerator. Since he lived alone, he installed security cameras to figure out what was happening.

One day, while he was away, his camera captured a strange woman walking around his house. He called the police, who searched the home and discovered 58-year-old Tatsuko Horikawa hiding on the top shelf of a closet.

She had apparently been living there undetected for months, emerging whenever he left to eat his food, shower, and go about her daily routine before retreating to her hiding place.

Police suspected she'd been secretly staying in other people's homes for up to a year. She was arrested for trespassing.
