Savanna's Act This bill directs the Department of Justice (DOJ) to review, revise, and develop law enforcement and justice protocols to address missing and murdered Indians. The bill requires DOJ to take the following actions: provide training to law enforcement agencies on how to record tribal enrollment for victims in federal databases, develop and implement a strategy to notify citizens of the National Missing and Unidentified Persons System, conduct specific outreach to Indian tribes regarding the ability to publicly enter information through the National Missing and Unidentified Persons System or other non-law enforcement sensitive portal, develop guidelines for response to cases of missing and murdered Indians, provide training and technical assistance to Indian tribes and law enforcement agencies for implementation of the developed guidelines, and report statistics on missing and murdered Indians. Federal law enforcement agencies must modify their guidelines to incorporate the guidelines developed by DOJ. The FBI shall include gender in its annual statistics on missing and unidentified persons published on its website.
