It happened at 2:15 a.m. Friday outside 7165, a bar and restaurant on the 7100 block of Germantown Avenue.
Police say a fight began brewing inside the establishment, where 20 people had gathered for an open mic night.
After the bar closed, the fight continued outside.
It ended when, police say, a man in his late 20s or early 30s pulled a handgun out of a maroon-colored vehicle, opened fire then fled.
"And that's when their was an argument. The argument turned into a physical altercation and that's when someone pulled a gun and fired," said Chief Inspector Scott Small.

"Oh my goodness. I just don't want this to become the norm," said Layla Muhammad.
Local business owners like Greg Locke of Vendors Boutique say this is still a safe part of town.
"There's too many innocent people being shot, too many, and it needs to stop, it really needs to stop. And that's the aggravating part, because this is a beautiful neighborhood," said Locke.
The owner of the bar says he feels terrible this happened, and as a result, it'll be closed until further notice.
Police are working to determine if the three male victims were involved in the original fight or if they were struck by stray bullets.
The suspect is described as a black male, late 20s to early 30s, brown complexion, with dreadlocks. He possibly retrieved the gun from a red- or maroon-colored car.
There are surveillance cameras inside and outside the bar and several witnesses to help in providing information.
