Tracy Daquan Bost - of Charlotte - was armed with a shotgun and fired at officers before he was killed.
"He ignored the multiple commands by law enforcement to relinquish his weapon and surrender, thus placing the officers in danger of great bodily harm and death. Officers returned fire which resulted in Mr. Bost's death," said Stanback in a statement after reviewing the SBI investigation of the shooting.
"Our deepest sympathies are extended to the family and friends of Mr. Bost. We know that this is a difficult time and this will be hard to accept, but it is a decision that is dictated by the evidence and the law," Stanback continued.
