"He has decided to testify on behalf of the state in this case," Howard told reporters. "What he has said to us that is within a matter of days he plans to make a statement regarding the culpability of officer Rolfe."

Howard also said that Rolfe kicked Brooks "while he laid on ground, while he was there fighting for his life" after he was shot.

Brosnan stood on Brooks' shoulders "while he struggled for his life," the district attorney revealed.

"Once Mr. Brooks was shot, there is an Atlanta policy that requires that the officers have to provide timely medical attention to Mr. Brooks or to anyone who is injured," he added. "But after Mr. Brooks was shot, for some period of two minutes and 12 seconds, there was no medical attention applied to Mr. Brooks."

That night, the pair of officers were dispatched to respond to complaints that Brooks was asleep in the drive-thru of the restaurant.
