Roommate Secretly Lived in the Walls

I discovered my roommate was secretly living in our walls for three months. Started noticing

weird things like food disappearing and strange sounds at night. Set up a camera

and caught him crawling through a hidden panel behind my closet. Turns out he moved

his girlfriend in without telling anyone and they built an entire living space between

the walls. When I confronted him, he acted like it was totally normal

and said he was saving money on rent. The landlord found insulation torn

out, wiring damaged, and a makeshift toilet system. Police got involved

because of the structural damage. He genuinely couldn't understand why everyone was upset.
