Grand Traverse County Sheriff Michael Shea said the “remarkable” efforts of the bystanders likely prevented others from being harmed.

Matthew Kolakowski was shopping for fishing gear and snacks with his daughter at a Michigan Walmart over the weekend when he heard an employee yelling “he's got a knife” followed by sounds of screaming.

Video footage from the incident shows bystanders confront the suspect after a stabbing rampage that initially left 11 people injured.
