TOWNSEND — A 19-year-old Townsend woman is being investigated by the Middlesex District Attorney’s Office in connection with allegations that she allegedly had sex with a 13-year-old boy in a hot tub at her home last month, according to Townsend police.

Police Chief Erving Marshall confirmed the allegations yesterday, but said much of the case is being handled by the District Attorney’s Office.

The name of the woman has not been released because she has not formally been charged.

According to a story on WBZ-TV, a 13-year-old boy hanging out with friends one night in July ended up at the 19-year-old’s house.

When the boy’s mother picked the group up later that night, one of his friends broke down in tears and told the mother what had happened, according to the report.

She immediately contacted the police, but no arrest was made. According to officials, the young teen’s friends confirmed the story.

Middlesex District Attorney Gerry Leone’s office would not comment on the matter, saying it could neither confirm nor deny that the office is investigating.

According to a statement released by Marshall, his office handled the situation appropriately.

“There is nothing unusual or out of the ordinary in how this case was/is being handled and the process and protocol that was and is being followed in this case has been well established within the Middlesex District Attorney’s office as any historical examination of these types of cases in Middlesex County would attest to,” the statement said.

The statement goes on to say that the complaint by the mother was received by police Friday, July 8, and two officers responded, one of whom “has significant training and experience in handling sexual-assault cases.”

The initial report was taken by the officers on scene. They contacted an on-call judge, who issued an emergency no-contact harassment order on behalf of the alleged victim. The state Department of Children and Families was also notified.

Marshall defended his officers’ decision to not arrest the suspect.

“While those that are unfamiliar with the process involved in these cases can be critical of how they are handled, the reason that they are handled the way that they are is in the best interest of the victims as well as in the best interest of these types of cases being successfully prosecuted and this case, in my opinion, is no exception,” Marshall said.
