A Rochester man picked up a 15-year-old girl in the vicinity of Fisherville Road in Concord and drove her to a nearby recreation area earlier this month, police said.

They parked and, in the rear seat of his white Dodge Ram, he touched her as he had done there before. However, on this occasion, they were interrupted by a Concord police officer patrolling the area. They hurried to gather their clothing before exiting the vehicle, according to court documents.

Jaythien Guillermo, 24, told police he had been communicating with the underage girl, referred to in court documents as Female Juvenile 1, through Snapchat over the course of the last two to three months. When he told officers his age, she overheard.

“You said you were seventeen?” she responded, according to a probable cause statement filed by officers requesting a warrant for Guillermo’s arrest.

One week later, the same day officers acquired the warrant, Guillermo turned himself in, according to the Concord Police Department. He faces one felony charge of certain uses of computer services prohibited and three charges of felonious sexual assault of a victim aged 13 to 15. He was arraigned in Concord District Court on Monday, June 15, when court documents show he did not enter a plea.

The nature of the crime makes Guillermo ineligible for bail.

On the evening of June 5, at around 10 p.m., an officer patrolling the Sewall’s Falls Recreation Area off of Second Street in Concord noticed a parked pick-up truck he initially believed to be unoccupied. At second glance, two individuals seated in the truck’s cab became visible, and the officer approached them on foot, according to court documents.

Both provided statements to the police before an officer transported the victim home.

Guillermo confided that he had been untruthful about his age and told officers that the victim had inflated her own age, telling him she was 17 or 18 years old. He acknowledged, nonetheless, that “there may be Snapchat communications during which FJ1’s true age was discussed,” according to court documents.

“In a historical sense,” the documents continue, “Guillermo advised that this was not his first interlude with FJ1.”

In separate statements to Concord Police, Guillermo and the victim acknowledged that he had made recordings depicting a sexual encounter. The victim told police these were filmed with her knowledge, according to court documents.

The officer who transported the victim to her family home obtained her written consent to seize and search her phone, which yielded data that corroborated their statements to police.

The case remains open and ongoing, according to Concord Police.
