Turpin case: Newly released 911 call reveals chilling moment tortured daughter turned parents in

A newly released 911 call reveals the moment a teenage girl sought help after she and her siblings endured years of severe abuse at the hands of their parents in their Perris, Calif., home.

As David and Louise Turpin await a Friday sentencing for torturing their 13 captive children, ABC News has obtained a recording of the 911 call the couple's 17-year-old daughter made to police, alerting them to the horrific situation.

"My parents are abusive," she can be heard telling the dispatcher. "My two little sisters right now are chained up right now ... they're chained up to their bed."

Both of the Turpin parents pleaded guilty to a total of 14 charges in February 2019, including a count of torture, multiple counts of false imprisonment, child endangerment and adult abuse. They face 25 years to life in prison if convicted.

Twelve of the couple's 13 children, who range from two to 29 years old, were discovered severely abused and malnourished in deplorable conditions on Jan. 14, 2018, after the 17-year-old girl escaped out a window and used an out-of-service cell phone to call 911.

Police initially believed the children were all minors and were stunned to learn seven were actually adults, ranging in age from 18 to 29 years old, who appeared younger due to their extreme malnourishment.

The victims were often chained to furniture and starved for extended periods of time and were only allowed one shower per year, according to court records.

Despite their abusive upbringing, the Turpin children are said to be in good spirits and are trying to heal and move on with their lives, according to their attorney, Jack Osborn.

"They’re not bitter. They really take every day as it is — as a gift," Osborn said on NBC’s "Today." "They want people to know that they are survivors."
