A six-person Assumption Parish jury convicted a Bayou L’Ourse man this week of indecent behavior with a 15-year-old girl, prosecutors said Friday.

Gary Jean “Ace” Foret, 57, 145 Jamie Court, Bayou L’Ourse, faces up to seven years in prison and up to a $50,000 fine on the indecent behavior conviction, 23rd Judicial District Attorney’s Office prosecutors said in a statement.

Jurors returned the unanimous guilty verdict Tuesday after a one-day trial at the Parish Courthouse in Napoleonville and 53 minutes of deliberation, prosecutors said.

Sheriff’s deputies arrested Foret on July 2, 2013, after the girl’s father reported that Foret had touched the girl inappropriately, prosecutors said.

The father told deputies that his daughter was supposed to spend the night at a friend’s house but ended up spending the night at Foret’s home in Bayou L’Ourse where he made the advance, deputies have said.

At the time of the incident, Foret was on parole for a 1975 second-degree murder conviction in Jefferson Parish, sheriff’s deputies have said. Foret had been sentenced to life in prison, but the sentence was later commuted to 60 years, of which Foret served about 20 years before his release.

Foret’s previous conviction was not raised at trial, however, and he did not take the stand in his own defense. The victim testified against Foret.

Judge Tess Percy Stromberg ordered a presentence investigation. Prosecutors said Foret, who has been out on bail, was ordered into custody Tuesday. Assumption Parish Sheriff Mike Waguespack said Foret was given a $100,000 post-conviction bail while he awaits sentencing.

The 23rd JDC encompasses Assumption, Ascension and St. James parishes.
