May 25, 2023 marks three years since 46-year-old George Floyd was killed by then-Minneapolis Police Officer Derek Chauvin outside the Cup Foods store in south Minneapolis.
Since then, Chauvin has been convicted of murdering Floyd and pleaded guilty to violating his civil rights. The three other officers involved in Floyd's death, Thomas Lane, J. Alexander Kueng and Tou Thao, were all convicted or took plea deals on state and federal charges as well.
Floyd's killing sparked weeks of protests and brought on a racial reckoning in communities across the country and around the world. In the three years after Floyd's death, the city of Minneapolis has attempted steps to improve accountability within its government and police department, created a Community Commission on Police Oversight, and updated its use-of-force policy to remove controversial restraint tactics.
Below is a day-by-day look at what happened in the aftermath of George Floyd's murder, from May 2020 to May 2023.

He's pronounced dead at a hospital.
