Prosecutors have said all 13 of the siblings were abused and most of them were held captive and tortured in their suburban Perris, California, home. The childrenranged in age from 2 to 29when their parents,David and Louise Turpin, were arrested in January.

At Wednesday’s preliminary hearingfor the Turpin parents, investigators with the Riverside County District Attorney’s Office who spoke with doctors treating the siblings at area hospitals painted a disturbing portrait of the debilitating long-term effects of the alleged abuse.

One of the adult female children was 35 lbs. underweight and suffered from “severe protein caloric malnutrition, numbness and weakness in extremities,” as well as “severe skeletal abnormalities,” investigator Wade Walsvick testified, based on his conversation with a doctor in the Corona Regional Medical Center who treated all seven adult siblings.

Like other siblings, the adult woman suffered from “low cognition and cachexia, a muscle-wasting syndrome,” Walsvick said.

The woman also had “severe skeletal abnormalities,” he testified.

Morris said on the stand that she was so skinny, her mid-upper arm “was equivalent to a 4½-month-old.”

He added that the girl had liver damage due to malnutrition and had “social dwarfism — a stunted growth damage due to malnutrition.”
