During closing arguments Tuesday, prosecutors say three members of a violent American Indian gang operated as a criminal enterprise and used witness retaliation among other tactics to maintain their reputation, the Associated Press reports.
The Native Mob started in Minneapolis in the 1990s and is most active in the Upper Midwest.
Wakinyon Wakan McArthur, the gang's alleged leader, and two others, Francis Cree and William Earl Morris are being tried in federal court on several charges including conspiracy to participate in racketeering and attempted murder in the aid of racketeering.
Prosecutors say the trio was involved in a conspiracy to sell drugs and commit violence in Minneapolis and the Cass Lake Area, MPR reports.
Of more than two dozen suspected mob members charged in a 57-count indictment in January 2012, McArthur, Cree and Morris were the only suspects that did not accept plea deals.
Defense attorneys say although gang members may have committed individual crimes, there's no evidence to support racketeering charges.
