An emaciated 17-year-old girl escaped a home in Perris, California, early Sunday morning where she had been held captive alongside her 12 brothers and sisters in filthy conditions, according to police.

Authorities arrived at the home to find several children shackled to beds with chains and padlocks, “in dark and foul-smelling” conditions, the Riverside County Sheriff’s Department said in a news release.

The parents, David Allen Turpin, 57, and Louise Anna Turpin, 49, have been arrested on charges of torture and child endangerment. Their bail is set at $9 million each. They were “unable to immediately provide a logical reason” why their children were shackled and chained, authorities said.

Sheriff deputies were “shocked” to discover that seven of the “children” in the home were actually adults, according to the news release. The ages of the 13 victims ranged from 2 to 29. They appeared malnourished and dirty, and told authorities they were starving.
