Victimization rates in Indian country are high in many parts of the country, particularly for crimes like sexual assault and domestic violence. In non-PL 280 jurisdictions, the federal government has concurrent jurisdiction with the tribe for many of these offenses. And, even in PL 280 states, the federal government may have jurisdiction to prosecute some intimate partner violence crimes occurring on the reservation. In each of these situations, it is likely that tribal personnel will be the first responders to the crime scene or to meet with the victim. This webinar will address how the federal government and tribal governments can work collaboratively to investigate and prosecute domestic violence and sexual assault offenses. We will cover the elements needed to prove the most commonly charged assault crimes in Indian country, special federal evidentiary rules that apply in sexual assault cases, and laws in the federal system that protect victims of domestic violence and sexual assault.
