It was a seemingly normal Saturday for Julia Martell, who was browsing the aisles of her local Walmart with a friend when she heard people screaming.

Stabbing suspect Bradford James Gille was subdued within minutes with the help of bystanders, authorities said.

After nearly a dozen people were stabbed at a Walmart in Traverse City, Michigan, Saturday afternoon, the quick actions of a couple of Marines and other bystanders helped stop the attacker from causing further harm.
