Witnesses describe Walmart stabbing in Traverse City, Michigan: Blood-curdling screams, a 'crazed' look

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.

TRAVERSE CITY, Mich. — 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.

Still, she didn't think much about the disturbance, assuming that there was a fight a few aisles over. As she turned the corner, she saw a man running down another aisle, and then she saw his knife.

Eleven people, ages 29 to 84, were injured in a stabbing attack at the Traverse City store Saturday, and a suspect was arrested.

Bradford James Gille, 42, was quickly subdued by other shoppers and taken into custody when a deputy arrived, the Grand Traverse County sheriff said.

The man barreled past someone else nearby and "angled toward me," Martell, 32, told NBC News. "And that's when I booked it down the aisle."
