(LOS ANGELES) — The desperate cry for help came from a girl who had lived in such isolation for 17 years that she didn’t know her address, the month of the year or what the word medication meant. But after jumping out a window from the filthy home where she lived with her parents and 12 siblings, she knew enough to punch the digits 9-1-1 into a barely workable cellphone and then began describing years of horrific abuse to a police dispatcher. The brave girl’s call that freed her siblings — some who had been chained to their beds — led to the opposite fate for their parents, David and Louise Turpin, who face 25 years to life in prison when sentenced Friday. The couple pleaded guilty in Riverside County Superior Court in February to torture and other abuse and neglect so severe it stunted their children’s growth, led to muscle wasting and left two girls unable to bear children. Before the 17-year-old escaped from the home in a middle-class section of the city of Perris, about 60 miles (96 kilometers) southeast of Los Angeles, the Turpins had lived largely out of view. David Turpin, 57, had been an engineer for Lockheed Martin and Northrop Grumman.
