The purpose of this legislation, known as the Justice for Murder Victims Act, is to allow federal authorities to prosecute homicide cases without being limited by the time that has passed between the act that caused a victim's death and the actual death itself. This aims to ensure that justice can be served even if significant time has elapsed since the crime occurred. Key provisions of the Act include the establishment of a new rule stating that there is no maximum time limit for initiating a homicide prosecution.
