HAHNVILLE — The St. Charles Parish District Attorney’s Office announced today Shelley Dufresne, one of two Destrehan High School teachers arrested last year and accused by authorities of having inappropriate sexual contact with a 16-year-old male student at the school, reaffirmed all of the terms and conditions of her felony plea agreement and pleaded guilty to a felony count of obscenity.

District Attorney Joel Chaisson II said the guilty plea was to a section of the obscenity statute that allows for the felony sentence that she originally received in April.

Judge Anne Simon resentenced Dufresne on the obscenity charge to a deferred term of three years in jail, three years of active probation and a $1,000 fine.

She is to have no contact with the victim or his family, forfeit her teaching certificate and complete 90 days in-patient mental health treatment in lieu of 90 days in parish prison.

The plea agreement calls for the original charge of carnal knowledge of a juvenile — which carries a potential 10-year jail sentence and mandatory registration as a sex offender — to be held open during the term of Dufresne’s probation.

As part of the plea agreement, Dufresne was once again required to admit to the factual basis for the charge.

If Dufresne fails to successfully complete her probation, she would be subject to further prosecution on the carnal knowledge charge and incarceration followed by mandatory registration as a sex offender.

Chaisson said the victim’s parents, through their attorney, expressed their support for this week’s court resolution.

Chaisson said he wanted to thank special prosecutor Julie Cullen for her efforts to reach a fair resolution and secure a felony guilty plea, “thereby sparing the juvenile victim in this matter from having to testify at a public trial.”

Dufresne of Montz was arrested Sept. 30, 2014, on a warrant for one count of carnal knowledge of a juvenile.

“Dufresne, who is a teacher at Destrehan High School, allegedly had inappropriate sexual contact with a 16-year-old student who attends Destrehan High School,” St. Charles Parish Sheriff Greg Champagne said during the week of the arrest. “The incident occurred in the early part of September at a residence in Montz.”

Champagne said St. Charles Parish Public School District officials first brought the reported incident to the attention of the St. Charles Parish Sheriff’s Office Sept. 26, when reports of a male student bragging to others about having a sexual relationship with teachers became public.

Kenner Police detectives arrested Dufresne and another DHS teacher, Rachel Respess, Oct. 1.

Kenner Police Chief Michael J. Glaser said each woman was booked with one count of felony carnal knowledge of a juvenile, indecent behavior with juveniles and contributing to the delinquency of juveniles for allegedly having group sex with the victim in September in Respess’ Kenner apartment.

“These charges stem from unlawful sexual acts with a 16-year-old victim that occurred at a residence in the city of Kenner on the night of Friday, September 12, and carrying over into the early morning of Saturday, September 13,” Glaser said in an October press conference.
