MINNEAPOLIS (AP) — Former Minneapolis police Officer Derek Chauvin has been convicted of murder and manslaughter in the death of George Floyd, the explosive case that triggered worldwide protests, violence and a furious reexamination of racism and policing in the U.S.

The jury reached its verdict Tuesday after deliberating about 10 hours over two days in a city on edge against another outbreak of unrest.

Floyd died last May after Chauvin, a white officer, pinned his knee on or close to the 46-year-old Black man’s neck for about 9 1/2 minutes.

The courthouse was ringed with concrete barriers and razor wire, and thousands of National Guard troops and law enforcement officers were brought in ahead of the verdict. Some businesses boarded up with plywood.

Floyd died last May after Chauvin, a 45-year-old now-fired white officer, pinned his knee on or close to the 46-year-old Black man’s neck for about 9 1/2 minutes as Floyd gasped that he couldn’t breathe and onlookers yelled at Chauvin to get off.

The jury, made up of six white people and six Black or multiracial people, weighed charges of second-degree unintentional murder, third-degree murder and second-degree manslaughter. Chauvin was convicted on all three counts.
