As the community learned of the loss, mourners visited the well-known nightclub to lay bouquets of flowers.

Records filed with the Georgia Secretary of State's Office showed Gidewon had worked as a nightlife entrepreneur for the past 35 years, Fox 5 reported. 

He and his younger brother, Alex, came to America after escaping violence in their East African home country of Eritrea. The brothers started as valets to learn the ins and outs of the nightlife business and eventually became knowledgeable enough to own their clubs, which were located a block from each other.
