The man at the center of a "Blue Alert" issued in Georgia is still on the loose, even though investigators discovered the car he was believed to be traveling in.

Brentson Thomas, 32, is wanted for allegedly critically injuring a detention officer and killing another person during a shooting near an apartment complex in Henry County Friday, authorities said.

Investigators found a gray Toyota they believe Thomas was driving after fleeing law enforcement, but did not specify where it was located.

Georgia "Blue Alerts" are issued to help arrest people suspected of injuring or killing officers. Anyone who sees the subject of a "Blue Alert" should not approach, but instead call 911 immediately.

"Mr. Thomas, I recommend you turn yourself in, because we will not eat, sleep, rest until we take you into custody," Henry County Sheriff Reginald Scandrett said. "Turn yourself in."
