A victim of human trafficking is sharing her heart-wrenching story with Iowans.KCRG-TV reports Kristina Glackin spoke to students in Cedar Rapids. For a week, as a teenager, someone held her against her will in a Los Angeles hotel, while they sold her body. Eventually a would-be 'John' rescued her. In the years since, she struggled to come to terms with what had happened. Her faith helped get her through it and prompted her to share her story."It gets easier each time. God has been faithful. I feel a responsibility to be faithful in sharing my story," said Glackin.Glackin was speaking as part of a nonprofit called Chains Interrupted. The group has been traveling around Iowa training hotel staff on how to spot a victim, and teaching kids how to avoid being one.
