LANCASTER (AP) — A woman found locked in a storage shed behind a Los Angeles County home appeared malnourished and had old and fresh wounds, investigators said Tuesday as the woman’s brother and his girlfriend remained held on charges of torture, abuse and false imprisonment.It was unclear how long the 54-year-old woman had been locked in the shed in the Mojave Desert city of Lancaster, about 40 miles north of Los Angeles.Evidence indicated that the woman may have been living in the shed for some time, and may have only recently been locked inside after a family dispute, said Sgt. Harold Morrow with the Los Angeles County Sheriff’s Department.Detectives interviewed the woman, but Morrow described her as a reluctant victim.“That’s what we’re trying to get to the bottom of — how long has this been going on?” he said. “We’re just trying to keep her cooperation and get to the story.“We’re still scratching our heads on the whole thing,” Morrow added.Deputies found the woman locked in the shed on Sept. 22 after getting reports of someone screaming. When they opened the shed, deputies described the woman as frail, malnourished and covered with wounds, prosecutors said.The woman’s brother, 61-year-old Elias Abdurahman, and his girlfriend, 50-year-old Sara Kebede Tadesse, were arrested and charged with false imprisonment by violence, torture, assault with a deadly weapon, and abuse of a dependent adult causing great bodily injury.
