The Florida man who allegedly ambushed and killed two Kissimmee police officers Friday night is a self-professed member of a black extremist group who appears to have been upset by last week’s events in Charlottesville, Va. Everett Glenn Miller, 45, was arrested and charged with first degree murder in the killing of Officers Sam Howard and Matthew Baxter. Miller, who goes by the name Malik Mohammad Ali on Facebook, allegedly ambushed and shot the officers as they were responding to a disturbance call.
