Four of the children living in the California house of horrors were seen less than two months ago looking 'very thin and very albino', a neighbor has said.
Housewife Wendy Martinez, 41, who lives in a home behind the single-story ranch-style property, told DailyMail.com she saw four of the children kneeling in the front yard late at night at the end of October.
She said the quartet looked emaciated and pale, and appeared to have been instructed not to respond when she tried to say hello to them.
'It was about 9pm at night and we came around right here and at the gate, we saw four children inside,' Martinez said.
'They were on their knees, four little kids, and they were just rolling on the grass. It was odd at that time of night.
'Their mother was in the archway, I just remember the mother in the archway, and I said, "hi". There was like no movement, not even to look over to see who's saying hi.
'No movement, like if they were told not to speak to anybody. The mom, no movement at all.'

Asked whether she thought the children needed help, she told DailyMail.com: 'Honestly, I didn't see like they needed help.
'They were in their yard. It was awkward that it was at 9pm at night but they were in their yard.'
David Allen Turpin, 57, and Louise Anna Turpin, 49, were arrested Sunday after 13 adults and children aged between two and 29 were found inside their four-bedroom Perris home.
Some of the children had been shackled to their beds and, cops said, were being held in 'a foul-smelling room'.
The Turpins purchased the house, which sits on a quiet well-to-do street, for $351,000 in August 2014 – later registering it as a school.
Sitting within a new development, the house had been a model home and was, said Dennis Cooke, 61, 'already tricked out with custom fittings' when they moved in.

Cooke, who works at Home Depot in Perris, said he had been shown around the property before the Turpins moved in, adding: 'This one was very beautiful, it was already tricked out with custom fittings, the backyard done, the landscaping done.'
But he said the spacious four-bedroom home is nowhere near large enough for 15 occupants, telling DailyMail.com: 'Oh no, no. Absolutely not. I would say a normal family, if they had six children, it could be adequate but 13, no. absolutely not.'
Although the Turpins were understood to be running a school from the house, neighbors said they saw no sign of parents arriving to drop off their children – and most said they had no idea that a young family lived in the property.
'You know what, I drive past this way every day but I've never seen the family or anything,' said nurse Janeece Calhoun, 21. 'Never anybody coming in or out.'
Neighbor Michelle Walls, 47, added: 'You would think you would have heard them. In our neighborhood, kids are usually out playing, shooting hoops. Going to the park.
'I'm surprised I never saw them because most kids need to go outside and play.'

Martinez says she last saw a member of the family a month ago, when she spotted one of the couple's teenage daughters drive past in a red Volkswagen Jetta, which was seen parked outside the home today.
She said: 'One of the girls was coming in in the red Jetta. They were in and out. I think it was one of the girls, I don't know which one it was, but as I was going out, she was coming in. She'd been out.'
Martinez added: 'It's weird – you never know what's going on. They've got three cars and that
