The 29-year-old weighed just 82 pounds and the other children are so thin they look younger than their ages, authorities said.
Almost six weeks after the siblings were rescued from the family's "house of horrors" in Perris, California, the six underage siblings have been discharged to live in two foster care homes, while the seven adult children continue to recover at the Corona Regional Medical Center. When they were liberated from their home in Perris, California, all but the youngest of the 13 children were malnourished.
The seven adult Turpin children are now recovering at a medical center in Corona, California, according to their lawyers.
The seven adults have the freedom to play outside, exercise, and use iPads at the hospital.
Lawyers Jack Osborn and Caleb Mason are representing the adult children and say they are learning to make decisions on their own for the first time.
"That in itself is a new experience for them, understanding that they do have rights and they do have a voice", Osborn said.
"They all have their own aspirations and their own interests and now they may have an opportunity to address those", Mr Osborn added. The couple, who allegedly starved and shackled some of their children, did not speak much in court, aside from agreeing to appear for a preliminary hearing in May.
The next court hearing is set for March 23 with a May 14 start date for the preliminary hearing but David Turpin's attorney, David Macher, noted that there is "a lot of evidence" so the preliminary hearing will likely be postponed. "They talk about how warm and loving these kids are and so appreciative", she said.
David and Louise Turpin are accused of abusing their children, including in some cases allegedly forcing them to shower only once a year, shackling them and beating them routinely, prosecutors said.
A spokesman for the Riverside County District Attorney's Office said the new charges included three counts of child abuse against both defendants.
Louise Turpin, 49, also was charged with one felony count of assault.
"Further investigations we have been doing in this case led us to amend the complaint, which is not uncommon", spokesman John Hall said outside court.
The Turpin brood was rescued in January from Perris, east of Los Angeles after the eldest girl escaped and called the police from an old cellphone she'd squirreled away.
The Turpin parents pleaded not guilty to 37 charges of child abuse, torture, false imprisonment, and imprisonment of a dependent adult.
Prosecutors then told the judge they planned to conduct the hearing under Proposition 115, meaning they would focus on testimony from investigators, not the kids.
Both defendants are jailed in lieu of $15.3 million bail until trial and prohibited from contacting their children. Their short-term goals are to see the beach, mountains, and a movie theater while over the long-term, they want to attend college and pursue careers.
