On Halloween night, somewhere between 2:15 and 3 a.m., 26-year-old Roberto Carlos Flores Sibrian crashed into a young woman’s car with his SUV on a dark Northern Virginia highway. Rather than call for help, Sibrian proceeded to haul the young woman from her car, drag her into a nearby ditch and rape her for two hours.

When he was done, Sibrian fled the scene, leaving behind both his shirt and his victim in the ditch. Battered and bruised, the woman was finally able to call for help.

Authorities arrested Sibrian three days later at the construction site in North Carolina where he worked and charged him with rape and sexual battery. The rapist, whose nationality wasn’t specified in local reports, was quickly identified as an illegal alien. He didn’t have a permanent address, but authorities said he’d been living in Fredericksburg, just over an hour’s drive from Immigration and Customs Enforcement headquarters in Washington, D.C.

According to NBC Washington, Sibrian is being detained in Lee County Jail in North Carolina on a $100,000 secured bond and an U.S. Immigration and Customs Enforcement detainer.

Stories like these are just one of the myriad reasons why many Americans are concerned about the administration’s repeated failure to enforce federal immigration laws. And the flow of unvetted illegal aliens streaming in from Central America – and a host of other nations worldwide – isn’t stopping anytime soon.

The first month of FY2017 set a 13-month high for border apprehensions. In October alone, Customs and Border Protection reported they apprehended 46,197 illegal aliens crossing into the United States unlawfully via the Southwest U.S. border, including 13,124 members of family units and another 6,754 unaccompanied children. Apprehensions in October were up by nearly 6,000 individuals from the heaviest month in FY2016, when 40,337 illegal aliens were caught back in May.

In fact, the number of family unit members apprehended in the first month of FY2017 is already 118 percent higher than those who were caught in October of last year.

Immigration officials said they’re currently housing about 41,000 illegal aliens in detention centers that typically accommodate between 31,000 and 34,000 people. The increased surge of aliens has caused border authorities to acquire new space to house individuals and increase personnel to keep up with the influx.

Most of these illegal aliens who aren’t from Mexico will be released into the United States with an order to appear before an immigration judge. More than half won’t show up to court.

Despite this open-border policy, Homeland Security Secretary Jeh Johnson insisted that “our borders cannot be open to illegal migration,” pledging, “[W]e prioritize the deportation of undocumented immigrants who are convicted of serious crimes and those apprehended at the border attempting to enter the country illegally.”

While it’s pretty safe to assume that not all illegal aliens caught at the border are rapists, the inability to vet each and every individual against criminal records in their home countries makes it nearly impossible to know who is a dangerous criminal and who’s not.

Unfortunately for Americans like Sibrian’s young victim, while these serious crimes may land an illegal alien in the deportation line (and even that’s not guaranteed), they’ll always leave behind an innocent victim.
