The trial for a former Melcher-Dallas High School teacher accused of sexual abuse has been postponed once again. 41-year-old David Bennett is now set to go on trial in Marion County District Court on May 7th. Bennett was arrested last year after being charged with one count of second degree sexual abuse and one count of third degree sexual abuse. The alleged victim was a juvenile female student at the time of the incident. Bennett had been set to go to trial later this month before the trial was delayed.
