Police say three people were shot following an altercation between a group of 8 men between the ages of 18 and 22-years-old, and a couple in the parking lot of the sports center on Gender Road.
According to officials, a verbal confrontation turned physical before the man pulled out a handgun and fired several shots at the group of men.
