MISHAWAKA — Prosecutors filed charges Tuesday against a former teacher who is accused of having a sexual relationship with a 17-year-old female student.

Dennis Jay, 36, was charged with three counts of child seduction. A warrant has been issued for his arrest.

Jay taught world history and coached varsity boys’ soccer at Elkhart Memorial High School before taking a position at Elkhart Central High School.

After receiving complaints about the relationship, the Elkhart Community School Board put him on administrative leave in September, then fired him after he continued to text message the girl.

According to a probable cause affidavit, Jay had sex with the girl, a student of his last year, at least three times between Aug. 1 and Oct. 31. The affidavit said another teacher living in the apartment below Jay complained about sex noises coming from Jay's apartment and the management at the apartment complex sent Jay notices about the noise.

The other teacher called police and told them he suspected Jay was having sex with a student because her car had a student parking sticker and a student identification card hanging from the rearview mirror. Police told him to call if he saw her again.

The teacher called and when police arrived they saw the girl coming out of Jay's bedroom and she appeared to be tucking in her shirt, the affidavit said.

The girl said she loved Jay and initially denied having sex with him. But when confronted with text messages about the sexual relationship, she admitted they had sex "three or four times," the affidavit said.

Jay faces six months to three years in prison and a fine of up to $10,000 on each count if convicted.
