With dozens of demonstrators in North Charleston protesting the fatal shooting there on Saturday (local time) of 50-year-old Walter Scott, which was captured on video by a witness, officials held a tense news conference expressing revulsion and appealing for calm.
"I have been praying for peace, peace for the family and peace for this community," North Charleston Police Chief Eddie Driggers said.
North Charleston Mayor Keith Summey told reporters that police officer Michael Slager, 33, had been fired. Summey said the remainder of the police force in North Charleston will soon be equipped with body cameras.
Slager was charged on Tuesday with murder in the death of Scott, the latest among several police shootings of black men over the past year in cities including New York; Ferguson, Missouri; and Cleveland, Ohio. The incidents have stirred debate across the United States about police use of lethal force and race relations, also drawing President Barack Obama into the discussion.
Police said Saturday's shooting occurred after Slager, who joined the department in 2009, stopped Scott for a broken brake light.
The Federal Bureau of Investigation and the U.S. Department of Justice are investigating Scott's shooting. Civil rights leaders called for calm, and many people praised the courage of the witness who filmed the killing and gave the video to Scott's family.
Holding signs that read "The whole world is watching" and "Back turned, don't shoot," protesters said Scott's death should not be viewed as an isolated incident.
The shooting was the 11th involving a police officer in South Carolina this year and the second in North Charleston, said Thom Berry, spokesman for the state's law enforcement division. No one was injured in the prior incident in the city in January, he said.
The video shows a brief scuffle between the pair before Scott begins to run away. Slager is then seen taking aim with a handgun before shooting eight times at Scott's back. Scott then slumps facedown onto the grass.
According to a police report, Slager told other officers Scott had taken his stun gun from him.
At no point in the video, which does not show the initial contact between the men, does Scott appear to be armed.
Slager is seen placing the victim in handcuffs as he lies on the ground, and then the officer walks back to a spot near where he opened fire.
The video then shows him appearing to pick something up, return to Scott, and then drop it next to him on the ground.
