Natalie White is a suspect in the arson and investigators are asking for help finding her, Atlanta Fire and Rescue said in a Twitter post.
The post included surveillance pictures of White in a store, but no additional identifying information.
Atlanta police officers were called to the Wendy’s on June 12 over complaints of a car blocking the drive-thru lane. Officers found Brooks asleep in the car.
The officers spoke to Brooks for more than 40 minutes, but things quickly turned violent when they tried to handcuff him, according to body camera video.
An autopsy found Brooks was shot twice in the back. Garrett Rolfe was fired from the police department immediately after the shooting and is charged with felony murder.
Protesters gathered the night after Brooks was killed, breaking the windows in the restaurant. A fire was set that destroyed the interior of the restaurant.
