DESTREHAN, La. – A bench trial centered on a Louisiana teacher’s sexual relationship with her student, and alleged threesome with another teacher, is shedding light on the details of the month-long affair.

Former Destrehan High School English teacher Shelley Dufresne this week faced up to a decade in prison and a $5,000 fine over a sexual relationship with a then 16-year-old football player at the school in August and September 2014, The Advocate reports.

Dufresne, who was 33 at the time, already pleaded guilty to sex with the student in St. Charles Parish and allegedly admitted to the same in Jefferson Parish, but her attorneys told Judge Danyelle Taylor on Tuesday the numerous sex romps only occurred in St. Charles Parish.

Dufresne received a deferred sentence of 90 days in a mental health facility and was not required to register as a sex offender in St. Charles Parish case, WVUE reports.

On Wednesday, Taylor found Dufresne not guilty on two counts of carnal knowledge of a juvenile.

“I do not believe that the threshold has been met by the evidence presented to this court,” she said, adding that the teen’s “braggadocios nature” and his “propensity to lie” created reasonable doubt, NOLA reports.

The now 19-year-old student took the stand Tuesday and said the relationship began during his junior year in the summer of 2014, when Dufresne contacted him on Facebook when he stayed home sick. The unidentified student said Dufresne teased him about being Mexican – he’s half Colombian and half white – and later created a fake Facebook account with the name “Madison Mexicano” and Speedy Gonzalez as the profile picture to communicate covertly with the teen, NOLA reports.

The student testified that the two first kissed in her classroom on Aug. 22, 2014, and she picked him up after a football scrimmage the same night and took him to an area near a daiquiri shop off Veterans Memorial Boulevard in Jefferson Parish for sex.

“Later on that night was the first time Shelley and I had sex,” the student testified.

The student told the court the two had sex at numerous other locations, as well.

“We had sex in multiple spots: the daiquiri shop in Metairie, off of Carriage Lane (in Destrehan) in a parking lot by some apartments,” he said, according to NOLA. “We also had sex in her house in Montz. We had sex right off of Brandon Hall (Drive, also in Destrehan), they have another parking lot. We had sex at (a friend’s) house in the shed in the back house. We had sex at Rachel Respess’ apartment in Kenner.”

Respess, a 25-year-old English teacher at the school, is currently awaiting trial on a charge of failure to report the commission of a crime.

Prosecutors allege text messages between Dufresne and Respess show they conspired to bring “you know who” to Respess’ apartment in Jefferson Parish for a threesome, and the teen admitted to taking cell phone video with his genitals on Respess as she slept on her couch after the alleged sex session, The Advocate reports.

“It was kind of like proof,” he said, explaining that he showed it to teammates on the Destrehan High School football team. “I told them about it, but they didn’t believe me.”

Dufresne’s attorney, Kim McElwee, pointed out that the teen’s description of the daiquiri shop where the two allegedly had sex in Jefferson Parish doesn’t match up to the actual location, and pointed out that Kenner Police relied heavily on the investigation from St. Charles Parish detectives to build their case.

She alleged Kenner Police “cut and pasted” information for Dufresne’s arrest warrant in Jefferson Parish, pointed out that the teen initially said the relationship started on Aug. 29, 2014 and not Aug. 22, and that the student told authorities the threesome didn’t involve actual intercourse because he couldn’t achieve an erection, which the teen denied on the stand.

“You didn’t tell the full truth,” McElwee told the boy.

The attorney also said that the video of Respess was illegal.

“You know it’s a crime to video someone without their permission?” she asked.

McElwee said the teen threatened to expose Dufresne when she corrected him in class, and highlighted the boy’s testimony that he thought he could leverage the relationship in her class.

“There have absolutely been no consequences for his behavior,” she said. “He thought, as a 16-year-old boy, that this was his fantasy, and he thought that this was pretty awesome and he bragged about it.”
