When police arrived at the home to investigate, they found the 17-year-old's 12 siblings allegedly shackled to their beds.
The six younger kids have been split up between foster homes.
More than a month after their parents' arrest, the siblings were undergoing treatment at multiple hospitals, the adults separated from the children.
The 13 children rescued from their parents' home in California in January are still on the road to recovery, but lawyers for the children say that the kids, for the first time in their lives, are beginning to make decisions for themselves.
The seven adult siblings are still recovering at the Corona Medical Center in California where hospital staff converted an area just for them, according to CBS, where they are being exposed to everything from "Harry Potter" to iPads.
The Turpins made a brief appearance in court on Friday, where neither spoke.
"That in itself is a new experience for them, understanding that they do have rights and they do have a voice", attorney Jack Osborn told the outlet.
The older children have plans to visit the beach, mountains and movies, and in the long term, attend college and pursue careers.More news: IAEA reaffirms Iran's compliance to nuclear deal for 10th time
"I just want you to understand just what special individuals they are", Osborn continued. 'They all have their own aspirations and their own interests and now they may have an opportunity to address those, which is really exciting'.
David and Louise Turpin look art each other as they appear in court for a conference about their case in Riverside, Calif., Friday, Feb. 23, 2018. The shocking crimes alleged in their case have been covered in state, national and global media - where the Turpin home has come to be known as the "horror house".
Spiegel described the young adult victims as "so loving and warm and affectionate", and said they appreciate the "things we take for granted".
A California couple charged with torturing their children by starving, beating and shackling them is due in court.
A spokesman for the Riverside County District Attorney's Office said the new charges included three counts of child abuse against both defendants. David Turpin was also charged with one count of a lewd act on a child under the age of 14 by force, fear or duress. He reiterated that both clients pleaded not guilty to the new charges and that "a lot of evidence" exists, likely postponing the preliminary hearing. She works closely with the siblings' nurses.
David, 57, and Louise Turpin, 49, entered not guilty pleas to torture and a string of other charges relating to the children, who are aged between two and 29. However, defense attorneys said they were skeptical they would be prepared to proceed on that date, considering the large amount of evidence in the case. They are each being held on $9 million bond.
They really hope that their identity is not going to be the past but what they are like now and like going forward, he said.
