Officials make case against US parents accused of torture and child abuse
David and Louise Turpin, from California, have pleaded not guilty to the charges.
Prosecutors have made their case against a California couple suspected of starving and shackling their children in a case that drew worldwide headlines when the parents were arrested last winter.
David and Louise Turpin appeared for a preliminary hearing in Superior Court in Riverside, where a judge weighed up whether authorities have amassed enough evidence for a trial.
The couple have pleaded not guilty to torture, child abuse and other charges.
They are being held on 12 million dollar (£9 million) bail each.
Louise Turpin wiped away tears as prosecutors played an emergency call from their 17-year-old daughter, who escaped the family’s home in Perris in January.
They're happy, they are wanting to move forward, they do not want to dwell on the past and they want their identity to be now and going forward the things they hope to do, the dreams they have Lawyer Jack Osborn on the couple's adult children
Authorities said their home reeked of human waste, and the evidence of starvation was obvious, with the oldest of 13 siblings weighing just 82lb.
The children were shackled as punishment, denied food and toys and allowed to do little except write in journals, prosecutors have said.
They said the children were isolated from each other and locked in different rooms in small groups.
They did not have access to televisions or radios but expressed themselves in the hundreds of journals that investigators seized from the home.
Most of the Turpin children were home schooled, but one of the older boys was allowed to attend classes at a local college.
His mother would drive him there, stay outside in the hallway during the class and then take him back home as soon as the class ended, prosecutors said.
After they were freed from the home, the children, who ranged in age from two to 29, were immediately taken to hospital and eventually released.
The current whereabouts of the children is unknown.
Jack Osborn, a lawyer appointed to represent the couple’s seven adult children, said earlier this year they were “doing well”.
They have participated in music therapy programmes and made crafts, while world-famous cellist Yo-Yo Ma held a special concert for them.
They communicated with their younger siblings over Skype.
“They’re happy, they are wanting to move forward, they do not want to dwell on the past and they want their identity to be now and going forward the things they hope to do, the dreams they have. They do not want people to think of them only as a possible victim, but as young adults setting off on their lives,” he told the Riverside Press-Enterprise newspaper in February.
Prosecutors are expected to call law enforcement officers to give evidence, but the children are not expected to appear.
David Turpin’s lawyer, David Macher, said he was “looking forward to the hearing”, but declined to comment further.
