TUPELO • A Houston man will spend the next 40 years behind bars for shooting and killing a Tupelo High School senior, just two days before he was to graduate in May 2020. According to testimony in Lee County Circuit Court Friday, Jacquez Dominique Calvert went to his car after a fight, pulled out an AR-15 and fired multiple rounds at Dreshawn Williams, 18, as he walked away. One of the bullets struck the high senior in the back of the head and he fell dead in the middle of the North Broadway Street around 8:45 p.m. May 5, 2020.
