A 42-year-old man entered the Traverse City Walmart around 4:43 p.m. on Saturday and used a folding knife to stab five men and six women, according to the Grand Traverse County Sheriff's Office.

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.
