A trial date has been set for Shelley Dufresne, one of two former Destrehan High School teachers accused of having sex with a 16-year-old student.

In a bill of information filed in November, St. Charles Parish District Attorney Joel Chaisson II charged Dufresne, 32, with one felony count of carnal knowledge of a juvenile. She pleaded not guilty and was released on a $200,000 bond.

During a pretrial hearing Monday, retired Judge Anne Lennan Simon, who is handling the case on an ad hoc basis, scheduled three days for a jury trial starting May 20 in 29th Judicial District Court in Hahnville.

The charge stems from an alleged sexual encounter with the teenager at a home in Montz. Prosecutors allege the sex occurred between Aug. 22 and Sept. 27.

If convicted, Dufresne faces up to 10 years in prison and a $5,000 fine.

Dufresne attended the brief hearing Monday with her lawyer, Deanne Williams, court records show. She’s due back for a status conference Feb. 18.

St. Charles Sheriff’s Office deputies arrested Dufresne in connection with the incident on Sept. 30. She was arrested again the next day by Kenner police, along with fellow teacher Rachel Respess, 24, for allegedly having a three-way sexual encounter with the student in Respess’ Kenner apartment after a Destrehan High football game in September.

In Jefferson Parish, the women were booked on identical charges of carnal knowledge of a juvenile, indecent behavior with a juvenile and contributing to the delinquency of a juvenile.

Neither Dufresne nor Respess has been formally arraigned on the allegations in Kenner. They’re due to appear separately in 24th Judicial District Court in Gretna in March.
