A former middle school teacher from Ohio has been found guilty of having sex with her 14-year-old student - described by a prosecutor as a 'stud' - inside a locked classroom last year.

Jurors reached the verdict on Friday afternoon after five hours of deliberation spread over two days. Jessica Langford, 32, was convicted of all six counts of sexual battery and unlawful sexual conduct with a minor.

As the verdicts were being read aloud, Langford broke down in tears and continued sobbing at the defense table for several minutes.

The presiding judge said she would remain free until her sentencing.

The victim, now age 15, took the witness stand on Thursday morning and recounted for the court how their sexual encounter unfolded on the last day of school in May 2017 inside a locked classroom at Miamisburg Middle school.

Guilty: Ex-teacher Jessica Langford, 32, broke down in tears in court on Friday after an Ohio jury found her guilty of having sex with her 14-year-old student

Langford, pictured in court on Thursday, was convicted of all six counts of sexual battery and unlawful sexual conduct with a minor

Langford was arrested last year for having sex with her then-14-year-old student inside a locked classroom. The encounter lasted up to 30 minutes

'We started kissing, she went in for a kiss and it escalated from there,' the teenager told the jury, according to a WHIO report.

According to the boy, he and Langford went on to engage in multiple sex acts, including intercourse and oral sex, for 20-30 minutes until the school principal knocked on the door of the locked classroom.

Langford allegedly told the minor to hide under a table and left with the principal. She later came back and allegedly told the boy to 'stick to the story' that he was in the room stacking desks.

“It felt uncomfortable...I thought it was wrong,’ the boy said of the classroom tryst.

Earlier in his testimony, the boy said he and Langford connected on Snapchat. When the teacher asked him why he reached out to her on the app, he said he replied that he wanted to have sex.

The defense questioned the student’s credibility, pointing to the fact that he had repeatedly denied having sex with the teacher last spring.

The now-15-year-old boy explained that he initially lied about his relationship with Langford for fear that his teenage girlfriend would break up with him for cheating on her.

Prosecutors said that Langford’s actions and words in her text messages were 'words and actions of guilt.'

The jury was handed the case on Thursday after a full day of testimony followed by closing arguments. They deliberated for 90 minutes before the presiding judge sent them home after giving them strict instruction not to discuss the case with anyone or seek outside information about the case from media reports.

Deliberations resumed at 9.30am on Friday and concluded at around 3.30pm, following a lunch break.

Langford, a married mother-of-one from Centerville, had taught math at Miamisburg Middle School for nine years, until she resigned her position in late May after allegations of sexual misconduct had come to light.
