This proposed legislation, known as the "Justice for American Victims of Illegal Aliens Act," seeks to modify federal statutes concerning capital punishment. Its primary objective is to introduce an additional circumstance that federal courts can consider when determining if a death sentence is appropriate for certain offenses. Specifically, the bill amends section 3592(c) of title 18, United States Code, by adding a new aggravating factor. This factor applies if the defendant is an alien unlawfully present in the United States and has been convicted of killing, attempting to kill, or conspiring to kill a United States citizen . This change would allow the defendant's immigration status and the victim's citizenship to be considered during the sentencing phase of capital cases.
