One person is in custody and another person, a companion of a second suspect, is hospitalized with non-life-threatening injuries. According to police, the second shooter is at large.

Police released a photo of the person they are searching for, saying at the time of the shooting, he was wearing a blue puffy jacket and tight dark jeans. They also asked that anyone who lives near Oakbrook Center check their security video for him or anything that might give information about the incident. Police were searching for the man in the area north of the mall near Roosevelt Road.

One of the suspected shooters, a man in his 30s, was shot “three to four times,” Police Chief James Kruger said. He underwent surgery Thursday night.

Three other people were also shot. Two women in their 40s were shot one time. A woman in her 20s was also shot one time. Another woman in her 20s fractured her ankle while running from the shooting, the police chief said.

As reported by CBS 2’ Asal Rezaei, Oak Brook Police say it took help from over 30 community law enforcement agencies to get things under control at the mall.

Michael Conroy was walking out of Hollister near the Amazon store when the shooting took place.
“I heard one pop, which made me turn my head, and then multiple pops,” he said. “I saw these sparks that were very bright. I assumed that it was a prank.”
Conroy said he believes he saw someone get shot and saw others around the area jump, but he was not sure if multiple people were shot.
“I just ran,” he said.
One shopper said a woman came running into the store where he was and alerted other shoppers inside to the situation.
“She runs in and she goes, ‘Guys, there’s a shooter.’ We all panicked,” Hoxhi Mulla told CBS 2’s Jermont Terry from outside the shopping center.
Phil Andrew, a security expert, and former FBI member explained that it will take some time for authorities to clear the mall as they go through to find pockets of people sheltering in place and make sure everyone is safe and can leave the area.

Oakbrook Center is an outdoor mall and major shopping center located near Interstate 88 and Route 83 in Oak Brook.
