A former school cafeteria aide accused of having sex with a student sent him explicit pictures and videos in the months before the incident, according to her arrest warrant. The warrant became public following Andi Rosafort’s arraignment in Danbury Superior Court, where she pleaded not guilty Wednesday. She’s charged with second-degree sexual assault, enticing a minor by computer and risk of injury to a child.

Rosafort, 31, of New Fairfield, worked at New Fairfield Middle School before her arrest. According to the warrant, that's how the victim met her. He told police, she was "his lunch lady when he was in eighth grade during the semester before summer 2022. He described how he and all of the students found her funny and personable."

In the warrant, the victim said he and Rosafort began communicating through Snapchat that summer, and she first sent him a nude picture via the app in September.

"The victim stated he was surprised he received a photo from her, so he stated he asked Rosafort if she meant to send the photo to him, and she then sent another photo. The victim stated that most times, Rosafort sent unsolicited photos and video," the warrant said.

The victim told police she asked him for explicit pictures as well. He also said she sometimes recorded him at his practices and game and sent the videos to him, according to the warrant.

Then on Jan. 13, while the victim was at a party with several friends, Rosafort allegedly messaged him asking to have sex. According to the warrant, he told police he made up an excuse to leave his friends, then Rosafort picked him up from a party, and they had sex in her SUV. "The victim stated he ended the encounter because he began to feel weird about it," the warrant said. He told police he got out of the SUV and ran back to the party. "The victim stated he immediately felt very weird and guilty about the encounter and eventually confessed to his parents the following Sunday that the encounter occurred."

According to the warrant, police corroborated the timeline with other teens at the party. One said the victim “looked nervous” upon returning from the encounter. Police said cellphone records put Rosafort in the area that night as well.

Police also viewed eight screen recordings on the victim's phone that showed sexually explicit videos of Rosafort sent through Snapchat, according to the warrant.

The warrant states Rosafort declined to be interviewed by police. She turned herself in on Feb. 20 and was released on $100,000 bond.

New Fairfield police first launched an investigation into Rosafort on Jan. 17 when administrators from the high reported “possible inappropriate behavior” may have occurred between a female school employee and a juvenile student. The investigation was initiated by the school resource officer and later taken over by state police.

According to the warrant, the first interview was with the father of a friend of the victim. He said his daughter had called him upset and said she’d been at a party with the victim on Jan. 13. The warrant said, “Juvenile1 stated the victim was acting strange and later found out the victim left the party to have sex with a woman she identified as the lunch lady, who the parent later identified as Andi Paige Rosafort. Juvenile1 told him that Rosafort is always talking to the freshman boys on social media."

In court Wednesday, the judge ordered Rosafort to stay off social media. A protective order was issued, prohibiting Rosafort from contacting the victim. She also can’t have contact with any minors except her own children.

She’s due back in court March 23.

Rosafort no longer works for the school district.
