Prosecutors have filed murder, assault and racketeering charges against a white supremacist prison gang called "Colorado's Aryan Brotherhood."
The indictments unsealed late Tuesday target 24 people inside and outside the prison system. All but two have been arrested.
Denver District Attorney Bill Ritter says prosecutors filed nearly 70 charges, which include witness tampering and drug counts.
Denver police detective Aaron Lopez says the gang, called the 2-11 Crew, has an estimated 300 members throughout the state's prisons.
Lopez says inmates were required to attack someone in order to join. If released from prison, they were required to send money to members still behind bars.
The money was most often raised through illegal weapons sales and drugs.
Lopez says the investigation began in 2003 after an assault in Denver.
The probe "exploded" when witnesses told Lopez about the 2-11 CrewHere is a list of members of the prison gang "2-11 Crew" indicted by a statewide grand jury for crimes including murder, racketeering, assault, witness intimidation and drug counts.
