Derek Chauvin, J. Alexander Kueng, Thomas Lane and Tou Thao have been charged in relation to the murder of George Floyd. Here's some of what we know about them.
Four police officers: Derek Chauvin, J. Alexander Kueng, Thomas Lane and Tou Thao. Four very different stories.
They ended up working together on Monday 25 May, after a 911 call came in from the Cup Foods Grocery store on Chicago Ave in Minneapolis when the staff suspected a customer had tried to purchase cigarettes with a counterfeit $20 bill.
Lane and Kueng were first on the scene and arrested the suspect, George Floyd, a 46-year-old black man, who was unarmed. They handcuffed him and were attempting to put him in into their squad car when Chauvin and Thoa arrived.
What happened next was filmed by a bystander. The police officers held Floyd down, with Chauvin kneeling on Floyd's neck for nine minutes, while he pleaded that he was unable to breath. Floyd eventually stopped speaking and went motionless. He was pronounced dead at a nearby hospital.

According to the police files, Chauvin received a letter of reprimand and a notice of suspension over an incident in which a woman said Chauvin had pulled her from her car, searched her and put her in his squad car after pulling her over for going 10 miles per hour over the speed limit. An investigator found he had no reason to take her out of her car.
Chauvin received recommendations that he receive a departmental medal of valour for his actions in two separate incidents: one involved shooting a man who aimed a shotgun at other officers, the other shooting a man suspected of violent domestic assault.
