(CNN) – Rayshard Brooks, shot while running from police, didn’t have to die, his family says.
The mayor of Atlanta agrees. On Monday, she called Brooks' death a murder.
Experts say the confrontation with police on Friday night could have been handled differently.
The family and the city are waiting to see whether the district attorney will file charges against the officer who fired three shots at Brooks and another officer who had been trying to arrest the 27-year-old man in the parking lot of a Wendy's.
Fulton County District Attorney Paul Howard told CNN's Anderson Cooper on Monday night that it comes down to what Brooks was doing when now-fired officer Garrett Rolfe pulled the trigger.
"The critical point that we are examining and the critical point I believe in this case is what happened at the exact moment of the shooting," Howard said.
If Rolfe shot Brooks, who was unarmed when searched but had taken a Taser from one of the officers, for any reason other than he was a deadly threat to others, then "it is not justified," Howard said.
The DA said there would be an announcement Wednesday on possible charges, which could range from murder to voluntary manslaughter.
