Police say a group of men got into a fight inside The Zone club at 163rd Street and Dixie Highway in Markham around 1 a.m., and that fight spilled into the parking lot.
"Through the investigation [and] during the night, security wound up involved with an individual that was starting a fight and subsequently escorted them out and when they were out in the parking lot, two individuals were shot and they were taken to the hospital," Markham Police Department Chief Mack Sanders said.
Authorities say someone then grabbed a gun and shot two people in their late teens or early 20s. One victim was shot in the chest and is in critical condition. The second man is in stable condition with a wound to his arm.
No one is in custody. Police are talking to witnesses at the club, which may have been holding a "college night."
