JM 9-65.900
The Violent Crime and Racketeering Section (VCRS) or Human Rights and Special Prosecutions (HRSP) Section (if international) has supervisory authority over 18 U.S.C. § 115. Consultation with HRSP is required before initiating an investigation if the matter involves international terrorism. The agency which would have investigative jurisdiction over an assault or murder of a particular Federal official will have corresponding investigative jurisdiction over an assault or murder of a member of that Federal official's family. In most cases, this will be the Federal Bureau of Investigation (FBI).
