While the military "quagmire" in Iraq was said to tip the scales of power in the U.S. midterm elections, most Americans have no idea more of their fellow citizens – men, women and children – were murdered this year by illegal aliens than the combined death toll of U.S. troops in Iraq and Afghanistan since those military campaigns began.

Though no federal statistics are kept on murders or any other crimes committed by illegal aliens, a number of groups have produced estimates based on data collected from prisons, news reports and independent research.
