Labyrinth beneath City of Industry home
 

Investigators find trap doors, a labyrinth of tunnels, and chambers with steel doors that lock from the outside

The City of Industry has closed off a house after investigators looking into building code violations uncovered a labyrinth of tunnels and rooms beneath it. Sheriff's deputies are now trying to figure out what could have been going on. Walk into the home on 17446 Renault St. and immediately your mind starts to wander to places normally only seen in horror movies. There are trap doors in the floor and tunnels to hidden chambers.
