The shooting occurred just before 6 p.m. in a corridor near a Nordstrom department store at the Oakbrook Center mall, Oak Brook police Chief James Kruger said. Authorities believe two people were engaged in a shootout.
“We believe that two individuals that were known to each other shot at each other, and potentially three would have been struck by gunfire either directly or by ricochet,” Kruger told Fox affiliate WFLD-TV.
An Oak Brook police officer working a detail at Nordstrom overheard the gunshots and radioed authorities. Both suspects ran into the Nordstrom in an attempt to flee, Kruger said.
