Following the stabbing of 11 victims at a Walmart store near Traverse City, Michigan, on Saturday, Grand Traverse County Sheriff Michael Shea said in a press conference that what bystanders did to stop the knife-wielding man was “amazing.”

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.
