A 32-year-old teacher at Destrehan High School was arrested Tuesday for allegedly having sexual contact with a 16-year-old student, authorities said.

Shelley Dufresne, who lives in Montz, was arrested about 5:30 p.m. by St. Charles Parish Sheriff’s Office deputies on a warrant on one count of carnal knowledge of a juvenile, sheriff’s spokesman Capt. Patrick Yoes said in a written statement.

Dufresne is the daughter of 29th Judicial District Court Judge Emile St. Pierre, according to the school district’s website.

School officials reported the incident to the Sheriff’s Office on Friday after the alleged victim reportedly bragged to other students that he was having sexual relationships with teachers.

The incident with Dufresne allegedly occurred in early September at a home in Montz, authorities said.

Additional arrests are possible. Stevie Crovetto, a spokeswoman for St. Charles Parish schools, said Monday that two teachers at Destrehan High School had been placed on leave with pay pending an investigation.

“The school system is conducting a thorough investigation of the allegations,” Crovetto said in an email. “We are being directed by our attorney. We have turned the matter over to the Sheriff’s Office.”

Sgt. Brian McGregor, a spokesman for the Kenner Police Department, said investigators are reviewing allegations about sexual contacts involving another teacher that may have occurred at a home in Kenner.

McGregor said the department is working with authorities in St. Charles and expects to release additional details on Wednesday.

Dufresne’s bond was set at $200,000 by state Judge Lauren Lemmon.

Dufresne, who is married and has three young children, graduated from Destrehan High in 2000 and LSU in 2005, according to the district’s website. She has taught at the high school for 10 years.

Information from the Sheriff’s Office’s website showed Dufresne had been released by 7 p.m. Tuesday.

This story was altered on Oct. 1 to reflect that Shelley Dufresne is 32, not 34.
