Arizona tribe protests lack of charges for border agents who killed Raymond Mattia

Leaders of the Tohono O'odham Nation say they may request congressional inquiry into Arizona state attorney's decision

Native American tribal leaders in Arizona are protesting a US attorney's decision not to prosecute federal border agents who shot dead an unarmed tribe member on their reservation in May.

Raymond Mattia was killed when the agents responded to a call for help by tribal police of the Tohono O'odham Nation after they received reports of shots fired in the Menagers Dam community near the US-Mexico border.
