This guy is crazy
The crazy, old Austrian dude at least created a sound-proof underground dungeon. This guy used tents. Tents!
"When did the Garridos get a kid?"
"Mind your business, bitch."
"Why is she living in a tent?"
"Maybe she likes to live in a tent."
"Why is she crying then?"
"MIND YOUR BUSINESS, BITCH!"
Seriously, how could you not call the cops? 
A neighbor did call the police, two years previously. He thought it was strange, called the police, who checked it out and did nothing.
The only reason they caught the guy is because he brought the two kids he begat on the kidnapped girl to pass religious literature out at UC Berkeley, and it seemed strange. He presented his ID which revealed him to be a sexual predator on lifetime parole. They arranged to meet with his parole officer (who had also been out to this ass clown's property several times and never known about his secret backyard), and the guy showed up with the two girls AND THE KIDNAPPED WOMAN, now 29?
And he apparently thinks this is going to be some kind of inspirational TV show eventually, maybe a miniseries on Lifetime.
Kill him now. He is a lifetime predator, and (considering one of the girls is 15) he got the kidnapping victim pregnant when she was 13 or 14, presumably repeatedly raping her from the time of abducting her at age 11. Insane. Feed him to the wild pigs.
