A bystander, armed with their own legally possessed gun, heard the gunshots and fired their weapon, hitting one of the suspects, police said.
The fight ended and the bystander waited for police to arrive.
The original armed suspect, who was injured in the shooting, was in the hospital in police custody. Police said the suspect is awaiting formal charges.
Two of the other males who were involved in the fight also suffered gunshot injuries. A female who was walking through the mall with her family was struck in the arm when the first shots were fired, police said. All of the injuries are considered non-life-threatening.
