SALEM, Mass. — In the course of investigating an alleged child rape involving a mom meeting up with a 15-year-old middle school student, investigators learned of a second alleged victim.

Heather Salines, 39, of Saugus was arraigned Tuesday on charges of aggravated rape of a child, indecent assault and battery on a child 14 or over, dissemination of obscene matter to a minor and child enticement.

A grand jury indicted her on those charges yesterday.

“The alleged rape and sexual assault took place in February 2014 in Saugus,” said Carrie Kimball Monahan, a spokeswoman for the Essex District Attorney’s Office. “The new charges involve a different 14-year-old.”

Monahan declined to give any specifics of the new case.

Prosecutor Kate MacDougall, working with state and local police, investigated this case. 

Two teen victims; similar details

The timeframe of both cases is similar.

In April 2014, Salines, then 38, pleaded not guilty to a charge of aggravated child rape during an arraignment in Salem District Court. She was released on $7,500 bail.

At the time, prosecutors said the married mother of two admitted to police that she took a 15-year-old middle school student to the DoubleTree Hotel on the Danvers/Middleton line and had sex with him there in March 2014.

MacDougall told the judge in this first case the boy was “vulnerable” because his mother had died and he had come to see Salines as a “mother figure.” The case came to light after Saugus middle school administrators learned the victim had shown another student naked photos of Salines on his cellphone.

In the second case, Salines is alleged to have raped a boy in her Saugus home. She allegedly sent explicit photographs of herself to that child as well.

After showing up at the school looking for the first boy on the afternoon of March 21, 2014, Salines agreed to speak with police.

“Things spiraled out of control,” she reportedly told police. “I lost myself.” The victim and Salines reportedly told police the pair had sex in a car and in the hotel.

In June 2014, an Essex County grand jury indicted Salines on six counts of aggravated rape and abuse of a child, a charge of child enticement and a charge of disseminating obscene material to a minor.

Each of the aggravated rape counts carries a 10-year minimum mandatory sentence. Salines and her attorney argued in February her rights were violated because she did not have a lawyer with her when she first spoke with police. A judge ruled that because she was not in custody by Danvers police while being questioned, her rights were not violated.

A final pretrial hearing is scheduled for July 28. The cases will be tried together beginning on Aug. 17.
