Authorities say 42-year-old Bradford James Gille walked into the store Saturday afternoon and began stabbing shoppers near the front checkout area with a folding knife. Victims ranged in age from 29 to 84, and one of them was a Walmart employee.

Matthew Kolakowski was shopping with his daughter at a Michigan Walmart when he heard screams and saw a man with a knife.

"I'm still sitting and grappling with the weight of realizing that it was kind of a life-or-death moment," said Julia Martell, who witnessed the stabbing, which wounded 11 people.

At least 11 people were stabbed in a horrifying scene inside a Michigan Walmart Saturday night — sending terrified shoppers and employees fleeing in all directions as bloodied victims collapsed across multiple departments, according to police and witnesses.
