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

"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.

Sheriff's deputies were unable to locate the man on Friday, a day before he allegedly stabbed 11 people in the Traverse City Walmart.
