One of the men who authorities say helped take down a suspect who stabbed eleven people at a Walmart told NBC News about how he sprung into action. Marine veteran Matthew Kolakowski says he took off running after the suspect and rammed him with a grocery cart to prevent him from hurting more people.

The suspect at times went off on tangents about cigarettes filled with fiberglass and seeing videos about psychotropic drugs.

Perry was captured on video confronting a Cheboygan man after he allegedly stabbed 11 people at a Walmart store in Garfield Township.

The suspect at times went off on tangents about cigarettes filled with fiberglass and seeing videos about psychotropic drugs.

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

A Walmart employee was helping a customer check out when she heard a warning that someone in the store had a knife.

A group of citizens, including a firearm-wielding Perry, confronted the suspect in the parking lot in a dramatic scene that was captured on video by a bystander. A deputy then took the suspect -- 42-year-old Bradford James Gille -- into custody, authorities said.

"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.
