Kate Steinle. Ronald da Silva. Sarah Root. Mollie Tibbetts. And most recently, amid the heated debates about border security, police officer Ronil Singh. These are just some of the names among countless other Americans who have been murdered by illegal immigrants — people who shouldn’t have been in the country, some of whom had already been deported and returned here anyway. Sadly, we can add four Nevada residents, three of them elderly, to that list: Gerald and Sharon David, Connie Koontz, and Sophia Renken, all of whom were allegedly murdered this month by Wilbur Ernesto Martinez-Guzman, a 19-year-old illegal alien.

Since Nevada is not a sanctuary state like neighboring California, law-enforcement officials were able to hold Martinez-Guzman on immigration charges while they collected additional evidence on the murder cases. Carson City Sheriff Ken Furlong said the suspect “was likely in the United States illegally and was detainable.” And Washoe County Sheriff Darin Balaam said authorities “feel confident” they have “evidence that will link him to all four homicides,” as well as burglary and possession of stolen property.

There are, of course, success stories of apprehending criminal illegal aliens before they harm any Americans. The Washington Times reports, “Zabi-Ullah Hemmat wasn’t just one of 415,816 illegal immigrants caught at the southwest border in fiscal 2016. Nor was he just another of the 84 people from Afghanistan apprehended by Border Patrol agents that year. … Mr. Hemmat is one of the terrorism suspects caught trying to sneak into the U.S. from Mexico.” Authorities found him on the no-fly list.

The Department of Homeland Security says 3,000 similarly “special interest” migrants were “encountered” by border agents in 2018. But, warned DHS Secretary Kirstjen Nielsen, “These are just the terror suspects we know about who reach our border.”

Exactly. But rather than secure our border, Democrats want to keep the government shut down and expand “sanctuary” cities. It’s worth noting that the vast majority of illegals truly are just trying to make a better life for themselves in America. Yet there are wolves among the sheep, and something must be done to keep them out.
