TWIN FALLS, Idaho (AP) — A 39-year-old Twin Falls man who had a warrant out for his arrest for breaking into his ex-girlfriend's house and threatening to kill her earlier this month is charged with a second attack in which the same woman said she was beaten, choked, raped and threatened with a knife.  Steven Ray Stone was arraigned Wednesday on six felony charges including rape, first-degree kidnapping, attempted strangulation and aggravated assault for Monday's attack. His bail was set at $500,000.  Court records say Stone has been charged with seven previous crimes over the past two years against the same woman.  The woman told police Stone was in her house when she got home at 6 p.m. Monday. She was able to call for help at 4 a.m. Tuesday after he fell asleep.
