A career counselor at the Medford Vocational Technical High School is under state investigation following reports she had sexual relations with at least two, but possibly three or more male students.

Jenna Tarabelsi, 29, is under investigation by the Massachusetts Department of Children and Families, said Jim Ricciardi, a Medford Police detective and resource officer at Medford High School.

“There’s not a whole lot for me to say right now,” Ricciardi said. “An allegation was made and it’s being investigated.”

Tarabelsi has not been charged or arrested with any crime as of May 12.

She could not be reached for comment at her home as of the Transcript’s Tuesday afternoon deadline.

The district placed Tarabelsi on paid administrative leave in early April after a student reported to a staff member that Tarabelsi had had inappropriate relations with a male student.

Medford Public Schools Superintendent Roy Belson said the district later received a similar report involving a second male student, and then another report about a possible a third male student.

Tarabelsi was placed on leave the same day on which the first report was made. Belson said the district notified the DCF and Medford Police after receiving the first report.

Rhonda Mann, a spokeswoman for the Executive Office of Health and Human Services, which oversees the DCF, confirmed the department was investigating a counselor at the school.

Belson spoke with DCF officials May 8 and said the department had interviewed the parents of students linked to the incidents. He said the district was assisting the DCF in its investigation.

“We’ve given all the materials — the personnel folders, records, everything you can possibly imagine — over to DCF,” Belson said Tuesday. “Yesterday, we turned over her iPad. They’ll look through everything.”

The district hired Tarabelsi as the Voke’s career counselor in December 2012. Belson said she was never disciplined during her two-plus years at the school until she was placed on leave in April.

Belson said the district found no record of Tarabelsi being disciplined during previous jobs, despite rumors he has heard circulating.

“Her references and everything were not indicative of that,” Belson said. “In fact, we had people telling us what a wonderful catch she was.”

Since the investigation was first reported May 8, Vocational Technical High School Director Heidi Riccio said the school had received an overwhelming number of media interview requests, which she said Belson was handling.

“It’s a very difficult spot,” Riccio said. “My biggest concern is obviously the students, so I like to keep things private for the respect of the students, and the staff as well. Because we’re all struggling with it.”

According to the district’s website, Tarabelsi received a master’s degree in school counseling from Boston College in 2012 and a master’s degree in teaching from Emmanuel College in 2009. She completed her graduate practicum in the Boston Public Schools.

From 2009-10, Tarabelsi spent one academic year at Arlington Catholic High School.

Principal Stephen Biagioni said she taught two or three sections of theology and was a part-time counselor for incoming freshmen.

“We never received any complaints from students or parents,” Biagioni said. “She was not re-hired, but it had nothing to do with any inappropriate behavior.”

According to the district’s website, Tarabelsi served as advisor for the Voke’s Key Club, a community service group, and as one of two advisors for the Vocational School Student Representatives, which elects senior class officers and organizes activities such as an annual food drive.

Belson said despite the public paying close attention to the situation, investigators and the district would not rush to judgment.

“The difficulty with this thing is that the rumor mill takes on a life of its own,” Belson said. “That only creates information which is not part of the investigation, that people will use to somehow characterize a situation. Medford is not immune from situations that happen in society in general. The issue isn’t that something can happen; it’s what do you do about it when it happens?”

Belson said the district handled the situation properly after receiving the first report of misconduct last month by placing Tarabelsi on leave and notifying the DCF.

“I’m confident that everyone’s doing what they need to do,” Belson said. “Our eyes are wide open on this. We’re not trying to hide anything.”

Belson said the DCF had not given him a timetable for completing its investigation.

“Obviously, they want to move as expeditiously as possible,” he said. “There’s a due process, and you have to respect that. Hopefully we’ll get an answer relatively soon and we’ll take the next steps to wrap up the situation.”
