Matthew Wyche, 20, and Hector Mejia, 20, are both charged with capital murder for the shooting of Peggy Ariza. Police say a group of men rang the doorbell at Ariza's home, forced their way in past her daughter, then shot Ariza as she was coming downstairs to check on the commotion.
The charges come just days after the arrests of two other suspects -- Keaton Cooper, 21, and Olen Ware, 20.
No bond has been set in the case.
