The teenager, who witnessed George Floyd's murder, during the trial of the white police officer told the court that she regrets not being able to save the black man's life.
Darnella Frazier was among the witnesses, who provided emotional testimony, at the high-profile trial of former Minneapolis police officer Derek Chauvin.
Frazier had recorded the viral video of Chauvin killing Floyd brutally, which sparked anti-racism protests around the globe.
'I have a Black father. I have a Black brother," Frazier told the court with tears running down her face. 'That could have been one of them,' she added.
In addition to this, another witness in the court said that he had made an emergency 911 call right after watching Floyd's death to report a 'murder.'
