MANDEVILLE, La. - A former Fontainebleau High School teacher and coach is accused of molesting one of his students.

William Leto, a former math teacher and assistant girls’ basketball coach, allegedly had sexual relations with one of his female students this past school year.

St. Tammany Parish Sheriff Randy Smith said Leto honed in on one 16-year-old girl, contacting her through social media and then escalating the relationship to a sexual encounter that included some incidents at the school.

"It's actually disgusting to think that someone in that position as a school teacher and coach here in our parish would take advantage of a child," said Smith.

According to the St. Tammany Parish Sheriff’s Office, investigators received an anonymous tip that Leto was having sex with a student. Detectives then conducted a forensic interview with the alleged victim, who told them that she and Leto had sexual contact on multiple occasions.

Leto is currently charged with four counts of Molestation of Juvenile by an Educator and one count of Computer Aided Solicitation of a Juvenile. Suzeneau said Leto could face additional charges as the investigation continue.

“It’s bad enough when someone takes advantage of a child. It’s even worse when it’s a person of trust, in this case, a teacher,” Smith said. “We will not tolerate this in our community, and anyone who thinks it’s ok, will be prosecuted to the fullest extent of the law.”

Additional victims or anyone with more information on this case should contact Detective Scott Davis at 985-276-1327 or by email at scottdavis@stpso.com
