13-year-old salina, just another girl next door, turned into a product, sold by pimps and used by men. >> i did all that. >> how old were you? >> 12. >> 12? >> yeah. >> she was caught in a casino by undercover police and locked up. according to the law, salina is a sex-trafficking victim, not a criminal. like most underage girls who are sex trafficked, she has a history of running away from home. that's a dangerous thing in cities across america where pimps are always looking out for girls who are out on the streets alone. >> here, at least, she is safe. >> what is it like when you are all alone in your room with yourself in your cell? >> it makes you think a lot and you get real depressed, real depressed i just want to cry. i cannot believe i am in here.
