Our son was at Oak Brook mall near the AMC theater when those shots were fired. They were walking up some stairs when a mall cop told them to turn around. Thank God they are OK. We are praying for everyone else there. They are trying to leave now.

Oakbrook mall event happened right in front of my girlfriend and I. To me, it looked like fireworks/crackers bc I saw a ton of sparks but idk my guns. We were walking out of Hollister. Stay safe everyone.

My daughter is locked inside Nordstrom. She said the shooter has been caught

My dad and stepmom are locked down in the Nordstrom right now. Apparently the shooter is in custody?

Thanks to @Nordstrom and their staff for helping us stay safe and calm as we are waiting out an active shooting at Oak Brook Mall. Thoughts and prayers to those involved.
