11 People Were Stabbed at Walmart — But One Man with a Gun Stopped the Massacre
In what began as an ordinary weekday morning at a Walmart supercenter in a quiet Midwestern town, a horrifying scene unfolded within minutes — one that could have ended in far more tragedy had it not been for the swift and courageous actions of a single armed civilian. What started as chaos soon became a tale of heroism, resilience, and the haunting fragility of everyday life.
The Attack Begins
It was just past 10 a.m. when customers at the Walmart in the outskirts of Jefferson County, Missouri, heard the first screams. Witnesses described a man, later identified as 28-year-old Marcus G., walking into the store calmly — carrying no visible weapons. Within minutes, he pulled out a large hunting knife from underneath his coat and began stabbing people indiscriminately in the electronics section.
“I thought it was just a fight at first,” said Erin Thompson, a mother of two who was shopping for school supplies. “Then I saw a man with blood on his face screaming, and people started running. It was pure panic.”
In the span of less than five minutes, Marcus had stabbed 11 people, ranging in age from 9 to 67. Among them were shoppers, employees, and even a pregnant woman. Several victims were critically wounded, one slashed across the neck, another stabbed multiple times in the back. There was no known motive — no words shouted, no warning given.
The Moment Everything Changed
Just as Marcus turned toward the checkout area, where dozens more customers were huddled and screaming, a man stepped forward with a firearm.
That man was James Whitmore, a 43-year-old Navy veteran and father of three, who had been in the adjacent aisle shopping for batteries. Whitmore, who had a concealed carry permit, had heard the chaos and drew his legally owned Glock 19 when he saw a man stabbing a teenager near the customer service counter.
“I had a split second to decide. He was charging at another lady, and I knew I couldn’t just wait for police. He wasn’t stopping,” Whitmore later told local reporters.
Whitmore raised his weapon, issued a verbal command for the attacker to stop, but Marcus ignored it. As he lunged toward another customer, Whitmore fired a single shot — hitting Marcus in the upper leg. When the suspect collapsed, Whitmore quickly moved in, disarmed him, and held him at gunpoint until law enforcement arrived just minutes later.
The Aftermath
Within eight minutes of the first 911 call, police and EMTs arrived on scene. Thanks to Whitmore’s intervention, the stabbing spree ended without any fatalities, though several victims were rushed into emergency surgery. The suspect, who survived the gunshot wound, was arrested and taken to custody for psychiatric evaluation.
According to authorities, Marcus had no prior criminal record but had a documented history of mental health issues. Investigators found rambling journals in his vehicle referencing isolation, voices, and feelings of persecution. There was no political or religious motivation detected at this time.
Jefferson County Sheriff’s Department praised the quick action of James Whitmore. Sheriff Don Hayes held a press conference, saying, “We are deeply grateful for the courage and responsibility shown by Mr. Whitmore. His actions likely saved numerous lives. This could’ve been a far worse tragedy.”
The Community Reacts
In the days that followed, the small town was rocked by the incident. Vigils were held for the victims, and donations poured in to help cover medical expenses. Many called for increased mental health services and security at large retailers, while others focused on the debate surrounding concealed carry laws.
Some viewed Whitmore as a hero. Others expressed discomfort with the idea of more civilians carrying weapons in public spaces. But few could deny the fact that on that day, Whitmore’s actions stopped a massacre from turning into something far worse.
“I don’t see myself as a hero,” Whitmore said in a quiet voice during a local TV interview. “I was scared. I just didn’t want anyone else to get hurt. I did what I thought was right.”
One of the victims, 19-year-old Julie Becker, who suffered two stab wounds to the arm and chest, credited Whitmore for her survival. “He saved my life. No doubt in my mind. I could hear him shouting before the shot. If he hadn’t acted when he did, I wouldn’t be here.”
A Larger Conversation
The event reignited national conversations about:
-
Mental health awareness and access to treatment
-
Security measures at major retailers
-
The role of armed civilians in emergency situations
-
The unpredictability of everyday violence
According to FBI data, stabbing incidents are on the rise in public areas across the U.S., though they still occur less frequently than gun violence. What made this situation particularly alarming was the randomness of the attack and how quickly it escalated.
Many pointed out that large retailers like Walmart — often crowded and minimally staffed — remain soft targets, where security is limited and response times can be crucial.
Legal and Policy Implications
Marcus G. is now facing 11 counts of attempted murder, aggravated assault, and use of a deadly weapon in commission of a felony. Prosecutors have ordered a full psychological evaluation before proceeding to trial.
As for James Whitmore, his actions were deemed legally justified under Missouri’s “Stand Your Ground” laws. No charges were filed against him, and he was released after giving his official statement to police.
Some lawmakers and community leaders have called for policies encouraging more rigorous mental health intervention systems, while others suggest it’s time for large stores to consider having armed, trained security personnel on site.
A Day That Could Have Been Worse
What happened inside that Walmart on a regular Tuesday morning was terrifying and traumatic. Eleven innocent people — some children, some elderly — suffered because of one man’s internal torment and a knife. But thanks to one bystander’s calm, courage, and readiness, the death toll was zero.
James Whitmore didn’t come to Walmart looking to be a hero. But when faced with danger, he made a choice — a difficult one — that stopped a tragedy in its tracks.
“I just wanted to buy batteries and get home,” he said. “Instead, I saw something I’ll never forget. But I did what I hope someone would do for my wife, my kids, if they were in danger.”
