One was a veteran of the Minneapolis Police Department who moonlighted as a security guard. The other provided security at a Salvation Army store, and spent some of his evenings at local clubs, working as a bouncer. In the year before their fatal encounter, George Floyd, 46, and the officer now charged with his death, Derek Chauvin, 44, worked at the same Minneapolis Latin nightclub, both part of the team responsible for keeping rowdy customers under control.
