George Floyd was murdered by police officer Derek Chauvin on May 25, 2020. Video footage from a cell phone camera showed even after he was handcuffed, and on the ground, Chauvin put his knee on his neck for 8 minutes and 46 seconds while he said he couldn't breath and pleaded for help. During the last three minutes Floyd was motionless and quiet. Three other police officers were there who restricted Flody's body movements and prevented anyone from intervening.

- George Perry Floyd was a 46-year-old black man. He did five years in jail for forcing his way into a pregnant woman's home and putting a gun to her stomach in a robbery. He had other criminal convictions as well. 
- Derek Michael Chauvin age 44, had been an officer in the Minneapolis Police Department since around 2001. Chauvin had 18 complaints on his official record, two of which ended in discipline from the department, including official letters of reprimand.
- Tou Thao, age 34. Six police conduct complaints had been filed against Thao, none resulting in disciplinary action. In 2014, Thao was accused of brutality when his arrest of an African-American man resulted in the man's broken teeth and hospitalization. The victim said he had been handcuffed without cause, and was then thrown to the ground and "punched, kicked, and kneed", and humiliated. The resulting excessive-use-of-force lawsuit was settled out of court for $25,000.
- Thomas K. Lane, age 37, and J. Alexander Kueng, age 26, were licensed as law enforcement officers in August 2019. Neither had prior complaints on their records.
Thao is Asian, Kueng is black, and Chauvin and Lane are white.
