Both he and George Floyd (ORDO AB CHAO chest tattoo) were brotherhood members, as are many police, of course, as Minneapolis Mayor Jacob Frey and Governor Tim Walz have been.
Both Floyd and Chauvin worked together as bouncers at El Nuevo Rodeo night club, which was just a block from the Police 3rd Precinct Station and just two buildings over from the International Order of Oddfellows. That establishment burn down shortly after Floyd died of an overdose of drugs (Take note, WaPo!).
The night club's owner curiously was on record as having said, "Let it burn!"
