The officer was responding to reports of an unarmed and unclothed man banging on doors and crawling on the ground.
 
"He tells me, 'I'm OK, I'm OK.' That's what he was saying," the witness said.
 
The witness said he told the man, identified as 27-year-old Anthony Hill, to go inside or he was going to get arrested.
 
"He was acting crazy, but he was calm like he didn't know where he was. He was like kind of lost in his face," the witness said.
 
The responding officer, who is described as a seven-year veteran, confronted Hill.
 
Some witnesses and the chief of police say Hill was aggressive and lunged at the officer.
 
"When the male saw the officer, he charged, running at the officer. The officer called on him to step back, drew his weapon and fired two shots," said DeKalb County Director of Public Safety Cedric Alexander.
 
Hill died at the scene. Some believe the shooting was justified while others aren't sure.
 
"He ran to the police. He runs wide open with the hands up," the witness said.
 
Hill was black and the officer is a white male. The chief says he wants a transparent investigation in light of officer involved shootings in other parts of the country.
 
The Georgia Bureau of Investigation has taken over the case to investigate.
