This bill amends federal law to permit the prosecution of homicide offenses regardless of the time elapsed between the act or omission that caused the victim's death and the death itself. This ensures that federal authorities can pursue charges even if a victim succumbs to injuries long after the initial incident, without superseding the general statute of limitations for initiating prosecution. A key provision establishes that the death penalty cannot be imposed for a homicide offense if more than 1 year and 1 day passes between the causative act and the victim's death, in which case the maximum punishment for first-degree murder would be imprisonment for any term of years or life. These changes apply to acts or omissions occurring after the bill's enactment.
