A Mt. Hermon man, who was convicted of sexually assaulting an 8-year-old boy at the Baton Rouge Zoo in 2013, was sentenced to 50 years in prison by a state judge in East Baton Rouge Parish on Thursday.

District Judge Beau Higginbotham gave Murry “Joey” Duncan Jr., 49, a sentence of 50 years — according to law he could have faced as few as 25 years or as many as 99.

Duncan must serve 25 years of that sentence without probation, parole or suspension of sentence, and must register for life as a convicted sex offender.

An East Baton Rouge Parish jury found Duncan guilty in October of committing sexual battery on a victim under the age of 13, during a church youth group sleepover at the zoo. At the time, Duncan was acting as a volunteer with the Bogue Chitto Baptist Church and was a chaperone for the youth group during its zoo visit on July 19, 2013.

Duncan also stood trial for the sexual battery of a 10-year-old boy at the zoo, but the jury found him not guilty on that charge.

Duncan must still stand trial in Washington Parish for crimes committed here, according to Chief Deputy Mike Haley of the Washington Parish Sheriff’s Office. Duncan was initially arrested by the WPSO in April of 2014 and charged with aggravated incest and pornography involving juveniles.

Haley said that Duncan’s second Washington Parish arrest was in May of 2014 for two counts of video voyeurism, molestation of a juvenile and pornography involving juveniles. As the investigation continued, Duncan was arrested for a third time in June of 2014 for an additional charge of molestation of a juvenile.

Overall, Duncan is alleged to have committed sexual offenses against seven juveniles.
