Salvadoran illegal immigrant caught and released under Biden now charged in Virginia mother's stabbing death

A 19-year-old Salvadoran illegal immigrant admitted into the country at the southern border under the Biden administration now faces a second-degree murder charge in the stabbing death of a 42-year-old Virginia mother.

Fairfax County Police arrested Alexis Antonio Cedillos-Campos on Wednesday in connection with the killing of Carmen Lizet Puch, whose body was found early Monday morning at Difficult Run Park in Great Falls, Virginia, one of the wealthiest communities in one of the most affluent counties in America. A jogger called police at approximately 6:45 a.m. after discovering Puch unconscious near a popular trail. Officers found her lying beside her car with stab wounds. Her body had been doused in gasoline. She was pronounced dead at the scene.

A federal source told Fox News Digital that Cedillos-Campos was allowed into the United States at El Paso, Texas, in April 2024 under the Biden administration's catch-and-release policy. He is now being held in a Prince George's County jail pending extradition to Fairfax County, where he faces the murder charge.

Puch, 42, lived in Reston, a suburb of Washington, D.C. She was a mother of a young daughter and worked at a nearby restaurant, the same restaurant where Cedillos-Campos also worked. People who knew her described her as soft-spoken and said she worked hard to support her child.

Police video shows suspect arming himself before the killing

Fairfax County Police Chief Kevin Davis laid out the evidence at a news conference, confirming that Puch and Cedillos-Campos had an "intimate relationship" and worked together. Davis said investigators recovered video footage from the restaurant showing Cedillos-Campos preparing before the attack.

Davis described what the footage showed:

"We have video footage of our suspect at the restaurant where he worked with our victim arming himself with a fixed blade knife, taking a pair of black latex gloves, taking a water bottle, and then off he goes with the intent to do harm and kill the victim."

The police chief did not hold back about what happened to Puch.

"The way that she was treated by this killer was reprehensible, to say the least."

Sources familiar with the investigation said Puch was stabbed inside her car. The case that Fairfax County police have assembled, a suspect caught on camera equipping himself with a knife and gloves, then traveling to the victim's location, points to a deliberate, premeditated act, even though the current charge is second-degree murder rather than first-degree. The details of the case are difficult to read, and harder still for the family left behind.

DHS and White House point directly at Biden-era border policy

Both the Department of Homeland Security and the White House responded to the killing by placing responsibility squarely on the immigration policies of the previous administration. DHS issued a statement to Fox News:

"Biden and Mayorkas hand-delivered alleged killer Cedillos-Campos to the streets of Fairfax County. They recklessly unleashed millions of unvetted illegal aliens into American communities and abused the law to do so. President Trump and Secretary Markwayne Mullin are now enforcing the law, arresting illegal aliens who have no right to be in our country, and have reversed Biden's deadly catch and release policy."

White House spokeswoman Lauren Bis was equally direct. She called the killing "100% preventable" and said the Biden administration "released this illegal alien" into the country. Bis pointed to what she described as "extreme Democrat politicians' open border policies" and their consequences, citing murders, rapes, and other violent crimes committed against Americans.

The timeline is straightforward. Cedillos-Campos crossed the border at El Paso in April 2024. Rather than being detained or removed, he was caught and released into the interior of the country. Roughly two years later, a Virginia mother is dead. The chain of decisions that put him on American soil, and kept him there, ran through the Biden administration's DHS. Fox News Digital reached out to former President Biden for comment. No response was noted.

This case fits a grim and growing pattern. Earlier this year, Fox News Digital reported on multiple homicides and other violent crimes involving illegal immigrants in Fairfax County alone. One of those cases involved Israel Flores Ortiz, an 18-year-old Salvadoran immigrant who entered the country illegally in 2024 and was convicted of assault and battery for groping several underage girls at Fairfax High School.

Spanberger dismantled Virginia's immigration cooperation on day one

The federal government's failure at the border is only half the story. Virginia's own state leadership has actively made it harder for local law enforcement to work with federal immigration authorities.

Democratic Governor Abigail Spanberger, on her first day in office, rescinded an executive order issued by her predecessor, Republican Gov. Glenn Youngkin, that had directed state law enforcement agencies to assist federal immigration authorities. Spanberger went further: she ordered state and local law enforcement to terminate all 287(g) agreements with ICE, cooperative arrangements that allow local officers to help identify and hold illegal immigrants for federal pickup. She also signed an order prohibiting ICE from using any state property as a staging area, processing location, or operations base for federal civil immigration enforcement.

In practical terms, Spanberger severed the working relationship between Virginia law enforcement and the federal agencies tasked with removing people who are in the country illegally. Fox News Digital reached out to the governor for comment on the Puch killing. No response was noted.

The consequences of sanctuary-style policies are not theoretical. When local jurisdictions refuse to cooperate with ICE, illegal immigrants who commit crimes cycle back into communities rather than into federal custody. DHS has documented this problem extensively, in one recent case, the department responded to a Democratic lawmaker's challenge by producing nearly 7,000 cases of sanctuary city failures.

Carmen Lizet Puch deserved better than a system that failed at every level

Carmen Lizet Puch was 42 years old. She was soft-spoken. She worked hard. She had a young daughter who now has to grow up without her mother. She was found beside her car in a park in one of the safest, most prosperous counties in the United States, stabbed and doused in gasoline.

The man charged with killing her should not have been in the country. A federal source confirmed he was caught at the southern border and released. He was not vetted in any meaningful sense that prevented this outcome. He was not tracked. He was not removed. He was handed entry to the United States and left to his own devices in a Virginia suburb.

The failures here are layered. The Biden administration's DHS caught Cedillos-Campos at El Paso and let him go. Governor Spanberger, upon taking office, dismantled the state-level cooperation mechanisms that might have given local police a tool to flag him to federal authorities. And now a mother is dead in a county park. The pattern of illegal immigrants admitted under Biden-era policies and later charged with violent crimes against Americans continues to grow longer.

Cedillos-Campos faces a second-degree murder charge. He sits in a Maryland jail awaiting extradition. The legal process will run its course. But no verdict will answer the question that matters most to the people who loved Carmen Lizet Puch: why was the man accused of killing her ever here in the first place?

Catch and release was always a policy with a body count. The only question was whose name would end up on the list next.
