Melissa Halstrom, of North Andover, is set to go on trial tomorrow for allegedly running a

prostitution ring out of her Elm Street home.
Police arrested her back in September 2007 after one of her “call girls” went to police.
Police say Halstrom employed four girls ranging from 16 to 18 years old. One girl was a 17-year-old from Andover.
Also on trial is her alleged business partner, Anthony Gorgoglione Jr., of Milbury.
Police say the pair ran a Web site where they posted photographs of the teens in various stages of undress, and conducting sexual activity.
The two are set to go on trial together in Lawrence Superior Court before Judge Kathe Tuttman.
