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. He had been involved in three police shootings, one of which was fatal. According to former club owner Maya Santamaria, Floyd and Chauvin both worked as security guards and had overlapping shifts at the Latin nightclub El Nuevo Rodeo. She said Chauvin had worked there for 17 years, while Floyd had worked at about a dozen events. She said it was not clear if they knew each other but that she did not believe so. Santamaria said Chauvin had sometimes used overaggressive tactics when dealing with black clientele, responding to fights by spraying the crowd with mace, a tactic she told him was "overkill".
