The police officer who fatally shot a black man in the US city of Atlanta could be charged by midweek, the Fulton County district attorney says.
Paul Howard said in a statement that his office would speak to two other witnesses before making the decision on filing charges against the officer, Garrett Rolfe.
The district attorney's office was also "experiencing some difficulty in obtaining all of the body cam and dash cam footage from the Atlanta Police Department," according to the statement on Sunday.
The officer shot Rayshard Brooks, 27, outside a fast food restaurant in the city on Friday night, after Brooks had resisted arrest and pointed a Taser at police that he had snatched from an officer, according to the Georgia Bureau of Investigation.
Brooks later died of his injuries.
"[Brooks] did not seem to present any kind of threat to anyone, and so the fact that it would escalate to his death just seems unreasonable," Howard told broadcaster CNN.
"If that shot was fired for some reason other than to save that officer's life or prevent injury to him or others, then that shooting is not justified under the law," he added.
The district attorney's office could decide to charge Rolfe with murder or felony murder, Howard said.
The shooting reignited protests against police brutality and racism in Atlanta that were sparked by the death of George Floyd in Minneapolis police custody last month.
Rolfe was fired, and Devin Brosnan, another officer involved, has been placed on administrative duties. Atlanta Police Chief Erika Shields also resigned.
