DES MOINES, Iowa (AP) — Iowa authorities say an 18-year-old sex trafficking victim who pleaded guilty to killing a man she said raped her escaped from a women’s center where she was serving her probation sentence. A probation violation report said Pieper Lewis was seen walking out of the women’s center early Friday, and her GPS monitor was later cut off. A warrant was issued for Lewis’ arrest and the probation report asked for her deferred judgment to be revoked. She could face up to 20 years in prison for killing 37-year-old Zachary Brooks in 2020. Lewis said she was trafficked to Brooks for sex and stabbed him in a fit of rage. Prosecutors didn’t dispute that she was sexually assaulted.
