An Iowa teen who was charged with killing her accused rapist has gone missing after she escaped her probation center, officials confirmed. 

On Friday, Pieper Lewis escaped the Fresh Start Women's Center after cutting off her electronic monitoring tracking device, Jerry Evans, the executive director for the 5th Judicial District, told CBS News in a statement. 

"At this time, her whereabouts are unknown," Evans said. "A probation violation report was filed on Friday recommending revocation of her probation. A warrant for her arrest was subsequently issued that remains outstanding."
