Bloomington police, who said no one was struck by the gunfire, are searching for two suspects after securing the scene shortly before 6 p.m. Thursday. Police Chief Booker T. Hodges said two groups got into an altercation inside a Nike store, one group left, but two individuals in that group returned and one of them fired three rounds into the store where customers were shopping.
A video posted on Twitter shows Busch walking away from the chaos while holding hands with his son, Brexton.
Busch's wife, Samantha, posted videos on her Instagram story, showing their son winning a youth racing event on Wednesday and riding roller coasters with her husband on Thursday before providing a sobering update after the shooting.
"If you are seeing the news about the @mallofamerica we got out and are safe," she posted. "Praying others inside are too."
Busch, the 2015 and 2019 champion and winner of 60 career Cup races, is scheduled to race Sunday in the No. 18 Toyota at Michigan International Speedway.
