A Covington man accused of the death of 7-year-old Ethan Israel Martinez was denied bond last week. David Joe Mann Jr., 25, was arrested and charged Sept. 20 in the death of the Livingston Elementary first grader, whose cause of death was listed as blunt force trauma to the head. Newton County EMS was initially called to the home Mann shared with Martinez's mother, the victim and the couple's 6-month-old daughter.
