A white Connecticut police officer who fatally shot a Black man in a mental health crisis was fired Friday as public outrage grew over videos showing he began shooting 30 seconds after arriving at the scene, where other officers had spent several minutes de-escalating the situation.

The officer’s firing came a day after the Rev. Al Sharpton and noted civil rights lawyer Ben Crump spoke at the funeral of the man who was killed, Steven Jones.

Hartford Mayor Arunan Arulampalam said he fired Officer Joseph Magnano because of what he saw on police body camera footage of the Feb. 27 killing.

The videos, released earlier this month by the state’s inspector general, showed that Jones was was on a city street holding a large knife, but that the first group of police officers who arrived backpedaled to keep their distance from him, spoke to him kindly, and seemed to have gotten him to calm down.
