IDAHO FALLS – The trial for a former Idaho Falls teacher accused of assaulting a student more than a year ago has been rescheduled. Former Eagle Rock Middle School teacher Jared Emfield, 46, is facing several misdemeanor charges for allegedly slamming a student against a wall and threatening him while pinning him to the ground. He was originally charged with one count of misdemeanor battery and pleaded not guilty last April. Additional misdemeanor charges were filed against Emfield in January, including one more count of battery, two counts of assault, a charge of false imprisonment and disturbing the peace.
