Evans was taken to North Fulton Regional Hospital, where she was pronounced dead.

Inniss was held at the scene by a witness who heard the gunshot, police said.

“At the time of the shooting, an armed witness who was driving by the bank heard the shot, got out to help, confronted the suspect, ordered the suspect to drop his weapon, and waited until our officers arrived on scene,” the post said. “A semi-automatic handgun was recovered at the scene.”

Inniss was taken into custody for questioning by Alpharetta detectives, Miller said.

Authorities learned "the victim and the suspect were in an on-again, off-again relationship that sadly ended in senseless violence during an argument” and charged Inniss with murder and aggravated assault with a firearm, according to police.
