He went on to acknowledge that they had been through a "traumatic ordeal" (to say the least!) but were "very friendly and cooperative" with the staff. Hestrin said the charges range from the year 2010 to the present, all alleged to have occurred in Murrieta and Perris in Riverside County.
On Thursday, David and Louise Turpin were charged with 12 criminal counts of torture, seven counts of abuse of a dependent adult, and 12 counts of false imprisonment that could keep them behind bars for life if they are convicted.
It took two years to carry out but last weekend a 17-year-old girl and her sister climbed out of the window of their Southern California home.
"My mum, who had let them date, ended up being the one telling the police they had to send her home", Robinette recalled, adding that their father was "so upset" with their mother for allowing them to date.
Detectives arriving at the house on Sunday in Perris, a town around 60 miles southeast of LA, they were horrified by what they found. Hestrin said they suffer from severe caloric malnutrition associated with muscle wasting.
Authorities believe that the 13 children imprisoned for years by their parents.
"It's very disturbing because I felt like I did know them", said Kent Ripley, the Elvis impersonator who led the parents through at least three vow renewal ceremonies in recent years - most recently on Halloween 2015.
Her suburban Southern California home served as a private school and a prison for the siblings aged 2 to 29.
Prosecutors said the abuse dated back years, to when the couple lived in Texas, and appeared to intensify over time.More news: Putin takes dip in icy Russian lake on Epiphany

Bail for the parents has been set at $12 million each.
Milligan said she was checking out Christmas decorations on nearby homes when she saw the older Turpin children putting up a Nativity scene outside their house and complimented their decorations.
David and Louise Turpin stand accused of holding their 13 children in shackles at their California home. She said that she was "shocked" and didn't see "any type of abuse" of their children. Hestrin said that one of the only things the children were allowed to do while in their rooms or chained up is to write in journals, which have been recovered by investigators who are "combing through them for evidence".
Prosecutors said the Turpins would buy food for themselves, leaving apple and pumpkin pies on the kitchen counter but forbidding their children to eat it.
Their 17-year-old daughter had been planning an escape with several other siblings for two years, Hestrin said.
Human waste in the house indicated the children were prevented from using the toilet.
David Turpin's lawyer, Deputy Public Defender David Macher, had only begun to investigate the allegations but said the case was going to be a challenge.
"Watching them now it's kind of haunting and disturbing", Mr Ripley said.
Prosecutors said the entire family would go to sleep around 4 a.m., sleep through the day and would be up all night. The Turpins allegedly forced the children to shower only once a year, shackled them and beat them routinely, Riverside County District Attorney Mike Hestrin said.
