Recently Dr. Laura Lederer, former senior advisor to the State Department of Trafficking in Persons, spoke at a Tulsa area church where she told the story of Rosa: America's wake up call to the human trafficking problem here in the United States. (Read the full story in our Recent Articles section.) Dr. Lederer said, "The Department of Justice is still collecting data concerning this problem and reports are inconclusive. For example, in Rosa's case, officials rescued 40 young women. By the time of the trial, only 14 girls testified. A couple girls returned to Mexico; others simply disappeared. One of the young women who did testify told us this trafficking ring had been operating for years and had victimized hundreds of women. Because we've only been tracking and prosecuting trafficking cases since 2000, and because convincing victims to testify is difficult, it's a challenge to get a true sense of the numbers of people impacted. That said, we know trafficking is widespread; the Justice Department's head of the new human trafficking unit told me they have a case of trafficking in every state of the country now."
