A judge has agreed to place 34-year-old Teri Mezzatesta on an electronic monitoring system so she can take care of her disabled grandmother at her Upper Chichester home.
Mezzatesta faces charges of statutory sexual assault, a second-degree felony, and false swearing in official matters by falsely incriminating another.
Mezzatesta claims she was sexually assaulted.
Mezzatesta was arrested on January 27 after, according to the affidavit, her son went to school officials about what he allegedly saw on the night of November 15.
In the affidavit, the 14-year-old son tells police he witnessed his mother having sexual intercourse with his 15-year-old friend who was over their home.
The son told police after he and his friend had been smoking pot, he fell asleep. Sometime later, he was awoken by the sound of his mother's voice.
That's when, the affidavit states, he walked into the living room and saw his mom and friend having sex.
The son punched his friend in the face and kicked him out of the house.
The affidavit says Mezzatesta told her son not to tell police because she could go to jail.
The son's friend soon returned and told him he had nowhere else to go and he allowed the friend to stay the night.
Because the friend's cell phone died, the son lent his friend his phone.
Two days later, the phone was returned to the son and he saw text messages between his friend and his mother that were of a sexual nature, the affidavit states.
The son then went to school officials who then contacted police.
The police interviewed the teen allegedly involved in the incident.
In the affidavit, the 15-year-old tells police he drove to a local tavern and purchased margarita coolers that night, which he and Mezzatesta drank on the porch before going back inside around midnight.
He told police Mezzatesta, who appeared drunk, asked him if he wanted oral sex and he agreed; this then led to intercourse.
According to the affidavit, the boy says Mezzatesta loudly instructed him on what to do which is when the son woke up and witnessed the two having sex.
However, Mezzatesta told police a different story, the affidavit states.
When interviewed by police, Mezzatesta allegedly claimed she was drinking that night and fell asleep on the couch.
She told police at around 2:00 a.m., she woke up to her son screaming and the 15-year-old friend on top of her.
Mezzatesta told police the 15-year-old had sexually assaulted her.
As a condition of the bail, Mezzatesta is prohibited from having any contact with minors.
