The mass stabbing start near the checkout lanes of a Traverse City-area Walmart store late Saturday afternoon, police said.

At least 11 people were stabbed in a bloody scene inside a Michigan Walmart Saturday night — causing terrified shoppers and employees to flee — before a brave armed citizen helped detain the knife-wielding maniac, according to police, witnesses and harrowing video.

Authorities say they plan to file terrorism and assault with intent to murder charges against the suspect in a weekend knife attack at a Walmart store in Michigan.

Viral video captures the moment Perry confronts the suspect, drawing praise from Traverse City residents and social media users alike.

"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.
