“Frosty Treats,” a Russian company operating ice-cream trucks near Kansas City, Missouri, promised a group of college students from the Ukraine the opportunity to earn salaries between $10,000 and $15,000 for the summer in the United States. Once in the United States, however, the students were forced to work 13 hours a day, seven days a week, for less than minimum wage. Defendants restricted the students' access to telephone and mail communication. On September 10, 2007, David Carslake pled guilty to obstruction of mail; Frosty Treats entered a separate settlement agreement, agreeing to pay more than $47,555 in restitution to the six students, and to stop recruiting foreign students at all of its U.S. locations for the next two years. Several of the other defendants remain at large.
