William Leto _lowres

William Leto, who formerly taught math at Fontainebleau High School and helped coach its girls' basketball team, was sentenced to five years in prison Monday for molesting a 16-year-old student.

Leto pleaded guilty to molestation of a juvenile by a teacher in 22nd Judicial District Judge Richard Swartz Jr.'s courtroom Monday, a spokeswoman for District Attorney Warren Montgomery said in a news release Tuesday.

The judge immediately posed the sentence, which Leto must serve without benefit of probation, parole or suspension of sentence. He will have to register as a sex offender for 25 years after his release, spokeswoman Lisa Page said.

Leto was arrested nearly a year ago when the St. Tammany Parish Sheriff's Office received an anonymous tip that the teacher and assistant girl's basketball coach was having inappropriate sexual relations with a female student.

A Sheriff's Office investigation determined that the complaint was valid. At the time, Sheriff's Office spokesman Daniel Seuzeneau said that Leto had made inappropriate contact with the girl  through social media and began “grooming” her.

The victim said she had sexual contact with Leto on multiple occasions, Seuzeneau said, but the molestation did not include sexual intercourse.

The case was prosecuted by Assistant District Attorney John Alford.
