The couple's children, including seven adults, are being cared for at local hospitals. Here is what the future may hold for the Turpin siblings:
Most of the Turpin children suffered from severe caloric malnutrition, and several have cognitive impairment as a result of abuse, Riverside County District Attorney Mike Hestrin said.
That means they were deprived of vitamins and minerals essential to their development, Dr. Roshini Raj, an associate professor of medicine at New York University, told HLN.
She said it may take a long time to get the victims to a healthy weight. "But it can be done," said Raj, an internist.
Doctors have likely checked for signs of infection before beginning the process of slowly feeding the children. "When you've been malnourished for so many years, your immune system is much weaker than it should be, and you're more prone to getting infection," Raj said.

"While there can be a number of complicated and interrelated medical, social and psychological disorders, there have been amazing and heartwarming examples of people who are survivors," Ochberg said. "We don't want to overemphasize hopelessness when everyone who cares about people like this are trying to find reasons to hopeful and optimistic."
Officials are working with the hospital to assess the adult victims and determine whether they can make decisions, said Mary Parks, a spokesperson for the Riverside County Department of Public Social Services. The agency will seek authorization and guidance from the court on who will provide care for the children, she said.
Foster care, possibly adoption
"When there are serious allegations of child endangerment, most likely child protective services will recommend a fast track to adoption," Heilman said. "However, there are times where the court may not want to make that ruling until it's further on in the criminal case."
The process to terminate parental rights is determined in dependency court, Heilman said, and birth parents have the right to contest the termination.
In the short term, the children will be placed in foster care, she said. Foster care parents could end up being the adoptive parents.
"We have a big push and responsibility to our children to see if there are any kinship caregivers ... that would be a viable option," she said. "In California, we tend not to terminate parental rights until we have an identified adoptive family."
Heilman said the goal would be to keep the siblings together, but that will likely be difficult.
"Throughout the country, there is a real need for families to step forward to become foster parents," Heilman said. "There's even a greater shortage of families that have the ability to take on siblings."
It may take at least 18 months to terminate parental rights and finalize an adoption.
In the meantime, Riverside County Department of Public Social Services is seeking court authorization to provide oversight and care for the 13 children and adult victims "to the extent that's necessary," the agency's director Susan von Zabern has said.

An attorney for David Turpin's elderly parents said she didn't "know whether or not" the grandparents would be able to provide for all of the siblings.
The elder Turpins, who live in West Virginia, "want to be very involved in trying to assist in placement," their attorney, Paige Flanigan, said. They are still trying to contact their grandchildren, she said.
Authorities don't know where the children may end up at this point, said Hestrin, the district attorney.
"We're going to do everything we can to assist them through our victims' services division, and hopefully they'll be cared for throughout this process," he said.
"They're relieved, I'll say that," Hestrin said.
