TRAVERSE CITY, Mich. (Michigan News Source) — When a man wandered around a Traverse City Walmart for half an hour on July 26 acting strangely, shoppers took notice. According to a new lawsuit, Walmart did not—and a father who threw himself between a knife and his kids is now demanding to know why.

Aaron Boudot, 41, filed suit December 2 in Grand Traverse Circuit Court, arguing Walmart failed to follow its own safety protocols after customers reported the suspect—Bradford Gille—behaving suspiciously for more than 30 minutes before the violence began.

Boudot was shopping with his wife and four children when he stepped between them and the attacker, suffering deep stab wounds that severed nerves and an artery in his arm. His attorneys say he still cannot use his right hand.

Witnesses reported that Gille paced the aisles without a cart, monitored security cameras, and carried a large backpack—behavior Walmart’s policies allegedly flag as a concern. Attorneys claim former employees told them they never received training on how to respond.

A Walmart spokesperson said the company will review the complaint and respond in court, emphasizing that customer safety “is a top priority.”

Gille faces 11 assault-with-intent-to-murder charges and a terrorism count. He remains jailed on a $1 million bond.

“My goal with this lawsuit is to hold Walmart accountable for my permanent injuries and the trauma my family endured, and to compel Walmart to make the changes necessary to prevent something like this from happening again,” Boudot said in a statement.
