Derek Chauvin has been sentenced to 21 years in prison for violating George Floyd’s civil rights.
Chauvin will serve the federal sentence concurrently with his 22.5-year sentence for murder and manslaughter.
The former police officer held George Floyd on the sidewalk outside a corner store in Minneapolis for more than nine minutes as he lay dying on May 25, 2020.
Chauvin was told by US District Judge Paul Magnuson what he had done was “just wrong” and “insulting”.
Mr Magnuson said: “I really don’t know why you did what you did.
“Putting your knee on a person’s neck until it’s expired is just wrong.”
Floyd’s brother Philonise also demanded the highest possible sentence.
He said: “My family and I were sentenced to life imprisonment.
“We will never get George’s life back.”
Federal prosecutors had asked the judge to sentence Chauvin to 25 years in prison.
Chauvin initially pleaded not guilty to the federal charges, but changed his plea in December.
Chauvin’s attorney Eric Nelson had asked for 20 years, arguing he was repentant.
However, he did not directly apologize or express remorse to Floyd’s family in court.
Instead, he told the family that he wished Floyd’s children “all the best in their lives” and that they had “excellent guidance on how to become good adults.”
For the first time, Chauvin admitted he kept his knee on Floyd’s neck, even as he said he couldn’t breathe.
The killing sparked protests against racism and police brutality around the world.
Mr Magnuson has not set sentencing dates for the three other officers who were at the scene – Tou Thao, J. Alexander Keung and Thomas Lane – who were convicted in February on federal civil rights charges.
