Heather Lasseigne Chiasson, a 29-year-old teacher at South Lafourche High School in Louisiana, is accused having sex with an unnamed 17-year-old male student, whom she taught last year.
Chiasson faces a charge of prohibited sexual conduct between an educator and a student, and has been suspended from her job. She faces a misdemeanor, rather than a felony, because the student was 17 at the time of the alleged incident, per Louisiana law.
Lafourche Sheriff Craig Webre said that police questioned the male student, who described a "flirtatious relationship" that allegedly escalated into sexual activity, including intercourse.
Webre said the student also showed police numerous text messages, some of graphic sexual nature, that were alegedly exchanged with Chiasson.
The school discovered the alleged relationship last Friday, according to school spokesman Floyd Benoit.
