Former Minneapolis Officer Derek Chauvin was convicted Tuesday of murder and manslaughter for pinning George Floyd to the pavement with his knee on the Black man’s neck in a case that touched off worldwide protests, violence and a furious reexamination of racism and policing in the U.S.

Chauvin, 45, could be sent to prison for decades.

The verdict set off jubilation around the city. People instantly flooded the surrounding streets downtown, running through traffic with banners. Cars blared their horns. Floyd family members who had gathered at a Minneapolis conference room could be heard cheering and even laughing.

The jury of six white people and six Black or multiracial people came back with its verdict after about 10 hours of deliberations over two days. Chauvin was found guilty on all charges: second-degree unintentional murder, third-degree murder and second-degree manslaughter.

His face was obscured by a COVID-19 mask, and little reaction could be seen beyond his eyes darting around the courtroom. His bail was immediately revoked and he was led away with his hands cuffed behind his back. Sentencing will be in two months.

Defense attorney Eric Nelson followed Chauvin out of the courtroom without comment.

As the judge asked jurors if they reached a verdict, a hush fell on the crowd 300 strong in a park adjacent to the courthouse, with people listening to the proceedings on their cellphones. When the final guilty verdict was announced, the crowd roared, many people hugging, some shedding tears.
