Greg Ramos wore a blank expression in court as he was arraigned for first-degree murder. The 15-year-old Florida boy allegedly confessed to strangling his mom over a bad grade. Police say Ramos and his mother got into a terrible argument after he came home with a ‘D’ in one of his subjects. After killing her, authorities say Ramos called two school friends, who allegedly helped him bury his mom, Gail Cleavenger, in a fire pit near a church. #InsideEdition
