BUHL, Idaho (AP) — Felony rape and first-degree kidnapping charges have been dropped against a south-central Idaho man initially accused of repeatedly raping and beating a woman and holding her prisoner for 18 months in a booby-trapped home.

The Times-News reports in a story on Wednesday that the Twin Falls County Prosecutor's Office dropped the charges against 36-year-old Oscar Ayala-Arizmendi on July 17. Prosecutor Grant Loebs says he doesn't have enough evidence to prove the allegations.

Ayala-Arizmendi's attorney, Keith Roark, says police did a poor job investigating and that the woman who made the accusations is a pathological liar. The 27-year-old Buhl woman reported on April 26 she escaped from a house in Buhl on April 8. Ayala-Arizmendi still faces a charge of felony meth possession. A trial is set for Nov. 17.
