A 9-year-old bystander who witnessed George Floyd's murder last year, then testified in court that she'd told a police officer to "get off of him" as Floyd died under Derek Chauvin's weight, is reacting to the guilty verdict that her words helped to secure.

Judeah Reynolds, now 10, was with her cousin, then 17-year-old Darnella Frazier, when they happened upon Chauvin sitting atop Floyd, who was facedown on the pavement in handcuffs with Chauvin's knee pressed against his neck. The killing occurred outside the Cup Foods store in Minneapolis, where the girls had gone to fetch snacks.

Frazier then filmed the incident on her phone, as Chauvin held his position for about nine minutes while Floyd grew unconscious and died, creating a visual record that served as the centerpiece of Chauvin's prosecution and helped ignite global protests over police brutality.

After watching the verdict announced Tuesday on TV, "My mom said that we brought change," Judeah told Good Morning America. "My dad said, 'We won.'"

The girl said she felt "kind of proud."

Prosecutor Jerry Blackwell highlighted both the video and Judeah's words in his closing argument. "Ultimately, it isn't really that complicated," he told jurors. "You can believe your eyes."

He added: "What it is you have to decide is so simple that a child could understand it. In fact, a child did understand it when the 9-year-old girl said, 'Get off of him.' That's how simple it was. 'Get off of him.' Common sense."

After less than a full day of deliberations, jurors found Chauvin, who was fired after his actions, guilty of all charges against him: second-degree unintentional murder, third-degree murder and second-degree manslaughter. He will be sentenced in two months.

"George Floyd we did it!!," she added. "Justice has been served"
