Officers pulled the stranger out of bed and took him to jail.
The resident, Peter Brownlowe, is a former Atlanta city police officer and an Army veteran.
"I was just on the bed sleeping like this and something woke me up," Brownlowe said.
Brownlowe said he didn't realize he had left the front door of his apartment unlocked and, in the middle of the night on Friday, he got the surprise of his life: A strange man, dressed only in underwear, in his bedroom.
"He came in the bed and was actually laying in the bed with me so I got up and came around and said, 'Hey, what are you doing?'" Brownlowe said.
The man didn't respond, but Brownlowe said he could smell alcohol. The former police officer called the cops instead of getting into a fight with the stranger.
The man was still sprawled out when two Duluth officers arrived. He didn't wake up until he was already in handcuffs.
"When I came out here, I saw his pants on my couch and his shoes are right there by the door and his cellphone is on top of his pants," Brownlowe said.
Police identified the drunken sleeper as Sangyul Jo, 34, and said he lives three buildings down.
"He could have actually killed me in that bed right there because I was actually asleep," Brownlowe said.
Brownlower knows he and Jo are lucky.
Police charged Jo with public drunk and disorderly conduct.
Records show he spent about 13 hours in jail and was released on bond.
