On July 27, 2025, a harrowing scene unfolded at a Walmart in Traverse City, Michigan, when a man unleashed a stabbing spree that left 11 people injured and sent shockwaves through the local community. What could have been a catastrophic mass casualty event was prevented thanks to the swift and courageous actions of two Marine veterans, whose presence of mind and bravery in the face of danger helped bring the violent episode to a prompt end. Their intervention not only saved lives but also reignited an important debate about the role of responsible, trained citizens in public safety.
The Attack: Chaos in the Walmart Checkout Area
The attack began shortly before 1:30 p.m. inside the bustling Walmart, located in one of Traverse City’s most frequented shopping areas. The suspect, later identified as 29-year-old Bradford James Gille, was armed with a folding knife and began stabbing shoppers near the self-checkout zone. As customers completed their purchases, they were abruptly thrown into chaos. Screams of terror reverberated as people fled for safety, some seeking shelter in aisles or behind displays, while others tried to assist the injured.
The victims, ranging in age from 29 to 84 years old, sustained multiple stab wounds to various parts of their bodies. Emergency responders arrived quickly after the first 911 calls and transported the injured to local hospitals. Medical professionals reported most victims were expected to recover, but the attack created a tense and somber atmosphere in the city as families and friends awaited news.
The Critical Intervention of Two Marine Veterans
Among the frightened shoppers were two men whose training and calm under pressure would prove crucial in halting the attack. Both Matthew Kolakowski and Derrick Perry are Marine Corps veterans residing near Traverse City. Their military backgrounds guided their responses as the situation rapidly unfolded.
Kolakowski sprang into action by using shopping carts as physical barriers to block the suspect’s movements. This tactic confined the attacker, limiting his ability to harm more people. The quick thinking showed a tactical understanding of containment techniques likely sharpened by military experience.
Meanwhile, Derrick Perry, who is legally armed with a concealed pistol license, took a decisive role outside the store. Perry drew his handgun and, along with others in the parking lot, verbally commanded the suspect to disarm and surrender. Perry’s steady and authoritative commands convinced the attacker to comply peacefully, dropping the knife without any shots fired. Perry held the suspect at gunpoint until police officers arrived and took him into custody.
In a later interview, Perry spoke modestly about his involvement:
“I ultimately wanted him to put the knife down and back away until law enforcement got there. … I just wanted everyone to be safe.”
Their combined efforts effectively ended what could have been a prolonged and deadly event. Their courage and composure gained recognition not only from law enforcement but also from the community.
Law Enforcement Response and Praise
Grand Traverse County Sheriff Michael Shea was quick to commend the actions of the bystanders. In a public statement, he said:
“I commend them. It’s not very often that we have citizens that are willing to step up and take action.”
The sheriff’s office credited the bystanders with preventing further injuries or potential fatalities, highlighting how ordinary citizens’ preparedness can sometimes make a critical difference in emergencies.
Following the incident, authorities charged Bradford James Gille with 11 counts of attempted murder and one count of terrorism. He was held on $100,000 bond. Investigators characterized the attack as seemingly random and reiterated that there was no known motive or prior connection between the attacker and any of the victims. Surveillance footage from inside the store, along with witness testimonies, became key pieces of evidence as the investigation continues.
Victims and Community Impact
The victims were quickly transported to nearby trauma centers. Doctors reported that most were in stable condition, and many were expected to make full recoveries, though some injuries were serious. Authorities have not released the victims’ identities, honoring privacy and allowing families the space to focus on healing.
In the days following the attack, the community of Traverse City rallied around the victims and the heroes who intervened. Local organizations and citizen groups began discussing ways to support the wounded – whether through fundraisers, donation drives, or outreach programs. The incident, while deeply unsettling, also brought a sense of solidarity to a community grappling with the shock.
Public Reaction and Discussion on Armed Civilians

News of the Marine veterans’ intervention spread rapidly on social media and local news outlets. Many expressed admiration for the veterans’ bravery and quick thinking, underscoring the importance of responsible gun ownership and preparedness in thwarting violent acts. The role of trained armed citizens in public safety became a topic of widespread discussion.
Some voices highlighted the benefits of having legally armed, trained individuals ready to act in emergencies, praising the veterans for their courage and discipline. Veteran groups and local leaders also praised their actions, framing them as embodying the Marine Corps ethos to protect and serve even beyond active duty.
Others, however, used the moment to raise concerns about potential risks, including the dangers of mistaken identity or accidental escalation in public confrontations. The incident rekindled ongoing debates about gun laws, self-defense rights, and public safety strategies. Legal experts reiterated that Michigan law permits concealed pistol license holders to carry firearms in most public venues unless specifically prohibited, and stressed that the veterans’ conduct appeared aligned with state laws and guidelines governing the responsible use of force.
The Importance of Training and Readiness
This chilling episode in Traverse City serves as a potent reminder that violent incidents can erupt anywhere and at any time – even in broad daylight and seemingly safe environments. The ability of the Marine veterans to remain calm and act decisively under extreme pressure is a testament to the value of training, discipline, and readiness.
Their actions underscore the importance of not only personal preparedness but also community awareness. Law enforcement continues to advise citizens to report suspicious behavior promptly and to act responsibly and legally if ever placed in emergency situations.
The courage displayed by Kolakowski and Perry exemplifies how experience and training can help transform a potentially deadly tragedy into an instance where lives are saved. Their example is likely to inspire conversation, training initiatives, and policies aimed at enhancing public safety through informed citizen involvement.
