BOSTON — Authorities in Massachusetts say three men have admitted to sex trafficking a minor.

U.S. Attorney Carmen Ortiz says 31-year-old Tyrell Gorham, of Lewiston, and two Brockton, Mass. men, 34-year-old Lee Young and 34-year-old Chelanjei Greene pleaded guilty Wednesday in Boston.

Prosecutors say Gorham recruited the minor from Portland and Gorham and Young transported her and a friend to Massachusetts to work as prostitutes. Greene helped the victims post advertisements online for sexual services.

The victims traveled to a Woburn motel to meet a client, who was actually an undercover law enforcement officer.

Sentencing is scheduled for Dec. 14. Gorham is expected to be sentenced to 12 years in prison. Young is expected to be sentenced to at least eight years behind bars and Greene to at least seven years.
