Roark was a close associate of the Black Guerrilla Family and received permission from them to start an organization to unite white inmates in the system.

The group grew in size quickly due to infiltration by a man named Michael Quinn, who had joined to secure protection for himself.

Initially, DMI worked for the BGF, but soon began offering those services to other gangs by targeting rivals and correctional staff.

They are infiltrating government organizations to tear them down from the inside, moving operations into small communities like Dundalk and Essex, MD, and taking advantage of the drug trade and murder-for-hire business where they are employed by other gangs for protection and "hits".

[citation needed] DMI member John Thomas Gordon was sentenced to 6 months for his participation in the January 6 United States Capitol attack.
