This is a study on the intergovernmental sharing of information and the development of an Inter-Governmental Tracking System (IGTS) for tribal communities to assist in prevention of domestic violence (DV) against American Indian and Alaska Native (AIAN) women. Crimes of DV are clearly present on reservations, but no statistics detail the rates of declination of prosecution by U.S. Attorneys (USA) for such crimes. The proposed project will respond to this statistical vagueness and provide statistics detailing specific prosecution rates for crimes committed against Indian women. The study will also consider the information flows associated with DV referrals and impediments to prosecuting non-Indian offenders in Indian Country cases.
