"The leasing people came, knocked on our doors," Brown testified. "It was like they had a noise complaint. And it was around like 2 p.m., which was kind of odd, because there wasn't no noise."
When both Brown and Jean — nicknamed "Bo" by his friends — came out of their apartments, they had their first conversation.
"Me and Bo were both smoking weed, and we kind of knew that (apartment management) was coming to our door because of maybe the scent of the weed."
The night his neighbor was killed, Brown left his apartment to watch part of a Falcons vs. Eagles game at a sports bar.
"My cousin plays safety for the Falcons, and a friend of mine plays for the Eagles. So I just wanted to make sure I was there to watch the game," Brown said.
But he decided to go home at halftime. He returned home to his fourth-floor apartment at nearly the same time Guyger walked into Jean's apartment, mistaking it for her own.
Brown testified he did not hear anyone say anything like, "Stop! Police!" But he said it was difficult to make out the brief and frantic words between Guyger and Jean.
When I come out (to) lock my door, I hear him," Brown testified. "I heard him singing every morning."
Jean apparently loved gospel music and Drake.
