Matthew Kolakowski was shopping with his daughter at a Michigan Walmart when he heard screams and saw a man with a knife.

Bradford James Gille, 42, is suspected of traveling from his home nearly 100 miles away to perpetrate the stabbing attack at the Walmart store in Garfield Township, just outside of Traverse City. He is slated to be arraigned soon on criminal charges that include attempted murder and terrorism.

O'Brien and Kolakowski, who are brothers-in-law, were visiting the Walmart to pick up supplies for a family vacation when the stabbing broke out.
