What do we know about Derek Chauvin?
Derek Chauvin, 45, had been a police officer with the Minneapolis Police Department for more than 19 years before George Floyds death. During that time, he was the subject of at least 22 complaints and internal investigations. One of the episodes led to two letters of reprimand  his only formal discipline. Mr. Chauvin worked in one of Minneapoliss busiest precincts on its most difficult shift, from 4 p.m. to 2 a.m., long after many officers his age had moved to different positions. He earned several awards, including two medals of valor after separate confrontations in which he shot at suspects, one of whom died. Mr. Chauvin, who is white, was filmed on May 25 of last year pressing his knee on the neck of Mr. Floyd, who is Black, for more than nine minutes as Mr. Floyd pleaded with him and repeatedly said, I cant breathe.  Mr. Chauvin was fired the next day, along with three other officers who had arrived at Cup Foods, a convenience store, after a teenage clerk called 911 to report that Mr. Floyd had used a counterfeit $20 bill. In October, Mr. Chauvin was freed from jail while awaiting trial, having posted $100,000 through a bail bond agency. He was initially required to remain in Minnesota, but later was allowed to live in any of the four bordering states (Iowa, Wisconsin, North Dakota and South Dakota) because of concerns for his safety.
