He said the 2-year-old boy got ahold of a loaded gun that was left out in a bedroom and shot his father Reggie Mabry, 26, in the back as he was playing video games in one corner of the bedroom. 

Initially, police believed the shooting was potentially suicide, but said the couple's 5-year-old, who witnessed the shooting, said his younger brother was the one who pulled the trigger.
