BRISTOL, Pa. – A Pennsylvania teenager is facing the equivalency of a felony charge in juvenile court after her phone was used to record sexual activity among two youth, and she allegedly shared the video through text message.

Acting Bristol Township Police Chief Ralph Johnson told The Morning Call that a 13-year-old student at Franklin D. Roosevelt Middle School was arrested and charged in juvenile court with an unspecified felony after she distributed what appears to be two underage youth engaging in sex.

Police did not release the girl’s name because she is a minor, but said her phone was used to record the illegal video before she sent it to numerous students, though authorities do not believe she recorded the video, according to the news site.

Bucks County District Attorney David Heckler said last month the sex act may be a case of incest, and the youth in the video may not have known they were being recorded. Sources told ABC one of the two participants in the video attends Roosevelt Middle School.

The case came to light last month when students were caught watching the video on their cell phones during a concert at the school. School officials notified police, who launched an investigation, as well as parents.

“The safety and wellbeing of the Bristol Township School District students is always out top priority, that’s why we are so disturbed by a situation that was brought to our attention yesterday,” Bristol superintendent Sam Lee told ABC in December.

Police confiscated about a dozen student cell phones as part of the investigation and concluded it was not recorded on school property. They plan to wipe the phones of the video before returning them, Johnson told The Morning Call.

No students were involved with recording the video, Johnson said, adding that the 13-year-old arrested for distributing the video was the only student charged in the case.

“It’s awful. It’s really very scary,” parent Colleen Costello told ABC. “Kids that young shouldn’t even be thinking about things like that today.”

Superintendent Lee said “we’ve taken initiative and effort to warn our students of the dangers of the situations like this we are encountering currently.”

The case is among the first to be prosecuted under a new Pennsylvania law that makes it a crime for minors to distribute nude images of anyone between the ages of 12 and 17, according to The Morning Call.

Even consensual exchange of explicit images, and self-portraits known as “selfies” are illegal, and both senders and receivers can face criminal charges.

“Minors who consensually exchange nude photos could face a summary charge, essentially a non-traffic violation … . A minor who receives a nude photo of another minor and shares it with others could be charged with a third-degree misdemeanor. Teens who distribute a nude photo of another minor without that person’s knowledge or consent could face second-degree misdemeanor charges,” The Morning Call reports.

“The law also allows for teens found delinquent – the equivalent of guilty in adult court – to enter a diversionary educational program and have their criminal record expunged.”

The episode at Roosevelt Middle School is at least the second criminal investigation under the new law.

“Middletown police are involved in an ongoing investigation into reports that students at Neshaminy High School shared sexually explicit photos via cell phone text messages,” according to The Morning Call.

“In that case, authorities believe between eight and 20 students could be involved.”
