The 211 Crew, also known as the Aryan Empire, Aryan Alliance or Brotherhood of Aryan Alliance is an American white supremacist prison gang, active both in and out of prison, that was formed in 1995 at Colorado's Denver County Jail. It was linked to several high-profile murders and criminal investigations. Those included the assassination of Colorado Department of Corrections head Tom Clements. Due to a threatening letter sent by a Texas Aryan Brotherhood member, it was suspected to be linked to similar assassinations of Texas district attorney Mike McLelland, and his assistant prosecutor Mark Hasse, but a former Justice of the Peace was eventually indicted for those murders.
