Dramatic video shows a heroic Walmart shopper armed with a gun confronting a knife-wielding maniac moments after he allegedly stabbed 11 people inside the Michigan store on Saturday night.
In wild cellphone footage shared on X, the brave man, identified by family members as Marine veteran Derrick Perry, is seen yelling at the suspected attacker to drop the weapon in the parking lot of the superstore in Traverse City, about 255 miles northwest of Detroit.
