Arrived at the ⁦@TheIACP⁩ conference this morning to see this vehicle which crashed into the McCormick Place earlier this morning. It appears it was a street race which resulted in the crash and there was one fatality. https://t.co/zpL8I7AicQ — David Molloy (@ChiefMolloy) October 26, 2019

McCormick Place security told the Chicago Fire Department that drivers were drag racing when one lost control and hit the building, the Chicago Sun Times reported.

Police said there was no impact on scheduled events at McCormick Place, which is the largest convention center in the U.S., with about 2.6 million square feet. It draws millions of visitors each year.
