Escambia County Sheriff’s deputies arrested a Pensacola couple after they sent their pit bull after two men yesterday. An argument that began on Facebook ended in a physical confrontation at the Lucky Penny gas station on West Fairfield Drive. 29-year-old Christopher Gentry and 34-year-old Emily Gentry made their pit bull attack the men as Emily Gentry held bystanders off with a stun gun. Both have been charged with aggravated battery.
