The Grand Traverse County Sheriff's Office is seeking to speak with witnesses in the stabbing attack at a Michigan Walmart.

A Michigan prosecutor filed a terrorism charge Monday against a man accused of stabbing 11 people at a Walmart store. The charge has been rarely used in the state's courts since it was adopted more than 20 years ago during the national outrage over 9/11.

Two Marine veterans played a key role in stopping a man who allegedly stabbed multiple victims in a Michigan Walmart. Matthew Kolakwoski had just left a checkout lane when he heard a worker scream that a man had a knife. He then heard a “mass of blood-curling screams from the back of the store,” mlive.com reported.
