U.S. Immigration and Customs Enforcement (ICE) did not adequately identify and track human trafficking crimes. Specifically, ICE Homeland Security Investigations (HSI) did not accurately track dissemination and receipt of human trafficking tips, did not consistently take follow-up actions on tips, and did not maintain accurate data on human trafficking. These issues occurred because HSI did not have a cohesive approach for carrying out its responsibilities to combat human trafficking. We made one recommendation to improve ICE’s coordination and human trafficking efforts to assist victims. ICE concurred with our recommendation.
