By the time an employee in the checkout area yelled about a man with a knife, it was too late. Nearly a dozen people had been stabbed at the busy Walmart in Traverse City, a tourist town on the shore of Lake Michigan,

Michigan authorities said Sunday they are seeking to file terrorism charges and 11 charges of assault with intent to murder against a 42-year-old man accused of carrying out a knife attack at a Walmart store.

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