Surveillance video reviewed by hospital staff showed the man leaving the hospital, Fields told Channel 2 Action News.
“They issued a code green and then later said they saw him leave the Pratt Street exit at 9:50,” Fields said.

Authorities at the time said Brittain has diminished cognitive abilities and limited vision in one eye. He was reportedly unable to speak or tell others what his name is.
“The blood clot affected his cognition,” said Fields, who lives in Newnan. “He couldn’t comprehend what people were saying to him and though he was trying to speak, everything would come out gibberish.”
The search for Brittain lasted through the weekend, and on Monday morning Fields and other family members were still handing out flyers near Grady.
“Walking around and showing people my phone and his picture and things like that, and some of the park areas,” Fields told Channel 2.
Simpson said it’s not clear where Brittain went after leaving Grady on Friday, but he was taken to Atlanta Medical by ambulance the next day.
“He’s been there in the hospital since Saturday, but he was unable to identify himself,” she said. “I guess he’d removed his Grady bracelet and didn’t have any other identification on him.
A doctor at Atlanta Medical contacted police after recognizing Brittain from flyers and news reports, his niece said. One of Brittain’s daughters drove to the hospital to be with him, she said.
Brittain’s family said he appears to be stable and is resting comfortably.
