Woman Accuses Idaho Man of Keeping Her as Sex Slave Woman says she was held 18 months, beaten with hammer and 2x4 By Kevin Spak, Newser Staff Posted May 16, 2014 12:01 PM CDT 71 comments Comments Oscar Ayala-Arizmendi (Police photo) (Newser) – Police found chains mounted to the wall and electric wire booby traps around an Idaho home, after a woman told them she'd been held captive there for a year and a half. Oscar Ayala-Arizmendi, 36, has been charged with rape, kidnapping, and possession of a controlled substance, the Twin Falls Times-News reports. His alleged victim, a 27-year-old who has not been identified, says that Arizmendi repeatedly raped her, and beat her with a hammer and 2x4 "more times than she could count." Arizmendi had installed a wooden and metal gate to his bedroom door, and at night would allegedly lock the woman in with him. She says he kept her "drugged up on meth," would lead her around the house on a leash like a dog, and would hold a gun to her head and threaten to shoot her. Escape attempts were severely punished, but she was allowed to leave the house a few times, returning under threat of death. She says she finally escaped on April 8 with the help of her brother and three other people, KSDK reports. But she didn't report her story to police until they arrested her on a drug charge on April 26.
