It appears this isn’t the first time she got too close to her students.

Former teacher Jennifer Fichter, 29, was locked up last week after her alleged sexual relationship with a 17-year-old student at the Central Florida Aerospace Academy in Lakeland, Fla., came to light.

Now she faces an additional 20 counts of unlawful activity with a minor for another alleged sexual relationship with a 17-year-old junior at the school. It lasted from October 2011 to May 2012 when she was 26, authorities said.

“We located our latest victim during our investigation at the school interviewing students,” Officer Carrie Eleazer of the Polk County Sheriff’s Office told the Daily News. “He did not come forward, we went to him.”

Their inappropriate relationship started in September when the boy would hang around her classroom after hours and they would text each other, Polk County Sheriff’s Office said.

The following month the teen started going to her apartment. Watching TV led to cuddling, which led to kissing and eventually sex, according to an affidavit.

The relationship ended for unknown reasons and authorities were unaware that it happened until Fichter was arrested April 14 for allegedly having a sexual relationship with the second 17-year-old.

That’s when authorities learned about the relationship from last year. He told police that he and Fichter had sex about 20 times in his bedroom while his mother was away from home, according to an arrest report.

There were other red flags in Fichter’s not-too-distant past about her alleged interest in teen boys.

In September of 2012, an officer conducted an interview with Fichter after she allegedly admitted to a co-worker that she was infatuated with a 14-year-old.

Fichter told the detective she stayed in touch with the teen on Facebook but denied there was anything sexual about their conversations.

“He was having family problems, school problems,” the English teacher said to the officer. “Sometimes there would be posts that were in relation to things we had discussed in literary terminology.”

The detective closed the case and determined “this incident did not rise to the level of any crime.”

Eleazer explained that the sheriff’s office notifies the school board every time they receive allegations against a teacher. The school board then conducts its own investigation.

Fichter was fired earlier this week and will have her first appearance in court on the new charges Thursday.
