Charges were brought against 19 people for allegedly pimping out underage girls and targeting young women in the state child welfare system.

The defendants were indicted for sex-trafficking minors, including some who were just 13, Manhattan federal prosecutors announced Thursday.

The men are alleged to have recruited at least 15 girls from a Westchester home for troubled and at-risk children, prosecutors say. The men are charged in eight different cases, and in one of them, two men, Ruben Morciglio and Carlton Vanier, were allegedly sex-trafficking from 2011 to October of this year. They are accused of using “means of force, threats of force, fraud, [and] coercion” to make the girls engage in “commercial sex acts,” according to a federal indictment.

Eight men were arrested and appeared in Manhattan federal court Wednesday, while 10 more were already in jail.

One defendant remains at large, according to officials.
