The 13 siblings who lived in a “house of horrors” with their alleged abusive parents were reportedly only allowed one meal per day and two showers per year, according to a law enforcement offcial .

NBC reports that the new details emerged on Thursday morning, hours before David and Louise Turpin were scheduled to appear in court on torture and child neglect charges. The pair is currently behind bars at the Robert Presley Detention Center in Riverside after their 17-year-old daughter escaped from the home earlier this week and told police about the horrific neglect and abuse taking place inside her parents’ Perris home.

When officers arrived to the home, they found the girl’s 12 siblings inside, some shackled to beds and lying in their own feces and urine. The victims, all children of David and Louise Turpin, range in ages from 2 to 29.

“They’re not being fed and they’re living in these filthy, dirty conditions,” Captain Greg Fellows of the Riverside County Sheriff’s Department said. “That’s going to take its toll.”

Law enforcement officials indicated that all 13 siblings are at local hospitals after authorities found them inside the home appearing weak, filthy, and emaciated. Medical professionals, treating the victims for “severe malnutrition,” gave them antibiotics, nutrients, and vitamins through an IV. Physicians reportedly expressed concern that the victims could go into shock from lack of food.

“It’s actually heartbreaking for the staff,” the Corona Regional Medical Center CEO, Mark Uffer said.

So far, the minor children haven’t been able to provide a formal statement to the police, aside from the teen girl who escaped the Muir Woods Road and explained the alleged abuse. Detectives are still working on getting formal statements from the adult children.

The suspects are expected to appear in court on Thursday. Check back with CrimeOnline as additional details become available.
