The man was captured in three minutes thanks to "citizen involvement," Grand Traverse County Sheriff Michael D. Shea said.

Authorities in Michigan say a man entered a Walmart in Traverse City on Saturday afternoon armed with a folding knife and stabbed 11 people before being stopped by shoppers and a sheriff's deputy. The attack began unfolding at 4:43 p.m., the Grand Traverse Sheriff's Office said in a statement posted online.
