Louise Turpin’s Sister and Brother Are Hoping to Adopt Youngest “House of Horrors” Kids (EXCLUSIVE)

It's been three months since David and Louise Turpin were arrested and charged with torturing and holding their 13 children captive. Now, Louise's sister Teresa Robinette and her half-brother Billy Lambert tell In Touch exclusively that they are trying to adopt the youngest six kids following their experience in the "House of Horrors."

"I want to. I'm at the point where I feel like I can help, so I would like to," Billy said before explaining how he hopes to talk to lawyers and Child Protective Services soon. "I think if we can keep them in the family and help them grow as a kid into an adult that would be great." However, Teresa points out that they might not be able to adopt the kids due to financial constraints.

"Me and my brother Billy were going try to adopt ourselves, just the younger ones, but we knew there was no way we were going to be able to take them on," Teresa, who has five kids of her own, added. "My main hope is that we can somehow, even if my brother and I are not able to adopt the kids, my main hope is just to be able to see my nieces and nephews as often as possible… That we get to have the relationship with my nieces and nephews that we've been wanting to have with them since the beginning."

While adoption is still up in the air, Billy has heard from the older Turpin siblings, who are currently living together in California, and revealed that they are doing well despite the circumstances. "They said that they were doing a lot better, eating better, and they seem very happy and upbeat," Billy said. "They seem very energetic and happy so them being away from David and Louise right now is a very good thing because I feel like they don't have those restraints that they had before."

The siblings, including sister Elizabeth, were all blindsided when their older sister was arrested last January and pled not guilty to more than 40 charges including false imprisonment, child abuse, and one count of lewd conduct with a minor. "I was just as in shock as everybody else," Teresa recounted to In Touch. "I felt like I was in a nightmare… just seeing that on the screen was just unreal. I just don't know how to describe it."

Billy agreed. "At the same time I was upset that [Louise] would do something like that — or David. To sit there and hurt a kid, especially your kid, but any kid in general, that's your blood. You're supposed to take a bullet for your kid, you're supposed to want to protect your kid, not hurt them. It was a big shock to all of us really."

Teresa and Billy wil share even more details about the family's "House of Horrors" in the Oxygen two-hour special The Turpin 13: Family Secrets Exposed on Sunday, April 28 at 6 p.m.
