Two men allegedly walked up to Wynn and his two friends, another man and a woman, and demanded money.
Wynn reportedly told the two suspects, "I ain't giving you s--t." The alleged suspects answered by opening fire, shooting Wynn once in the head.
He was pronounced dead at the scene.
The two suspects reportedly ran into the nearby apartment complex, where they robbed a person in the lobby, according to cops. That victim was not injured.
The muggers then fled the scene. No arrests were immediately made.
