Illegal Immigrant Released Under Biden-Era Policy Charged with Murdering Virginia Mother

Fairfax County police arrested Alexis Antonio Cedillos-Campos this week and charged him with second-degree murder in the killing of Carmen Lizet Puch, a 42-year-old mother of a 3-year-old girl, according to Fairfax County police and reported by FOX5 DC.

Police say Cedillos-Campos confessed to the killing after his arrest.

According to police accounts, Cedillos-Campos left his restaurant job in the early morning of August 17 carrying a knife, gloves, and a bottle filled with gasoline he had siphoned from his motorcycle. He then went with Puch, a coworker at the same restaurant, to a park in Great Falls, Virginia.

Police allege Cedillos-Campos stabbed Puch to death at the park, then poured gasoline on her body and set it on fire.

Puch's friends set up a GoFundMe campaign to support her young daughter. "Her gentle spirit, kindness, and strong work ethic made a lasting impact on everyone around her," the fundraiser page reads. "She was soft-spoken, caring, and always looking out for others, often asking how people were doing and offering help without hesitation." The page notes Puch had moved from New Jersey and was "working hard to build a better life for herself and her young daughter."

FOX5 DC reported that Cedillos-Campos, a national of El Salvador, illegally crossed the U.S.-Mexico border near El Paso, Texas, in April 2024. Border Patrol agents apprehended him at the time, but he was released into the U.S. interior under the Biden administration's catch-and-release enforcement approach rather than being detained pending removal proceedings.

That policy allowed many migrants encountered at the border to be released while awaiting immigration court dates often scheduled years out. It was a defining feature of border enforcement during the Biden administration and a persistent target of criticism from Republicans and immigration hawks. Critics argued the practice let people with unresolved legal status, and in some cases undetected criminal histories, live and work in American communities for years without further vetting. Defenders of the policy, including some Biden administration officials at the time, argued that mass detention was not logistically or legally feasible given court backlogs and detention capacity, and that most migrants released under the policy showed up for their court dates and committed no crimes.

Both things can be true at once: the vast majority of people released under catch-and-release policies do not go on to commit violent crimes, and a case like this one still represents a preventable tragedy if screening or detention had been different. No national data cited here proves the policy caused this specific outcome beyond the timeline itself, but the timeline is not in dispute. Cedillos-Campos was apprehended, released, and is now charged with murder roughly 28 months later.

This case has not yet gone to trial, and Cedillos-Campos has not been convicted of anything. The second-degree murder charge is an allegation, and he is entitled to a legal defense and due process like any other defendant. No information in available reporting indicates he had a prior criminal record in the U.S. before this alleged killing.

The case adds to a running list of high-profile crimes committed by people who entered the country illegally and were released rather than detained. This pattern has fueled political pressure on both the Biden administration's legacy immigration policies and on the current Trump administration to show measurable results on interior enforcement and deportations of those already inside the country without legal status.

Fairfax County prosecutors have not announced a trial date. The case will proceed through Virginia's court system, where Cedillos-Campos faces a second-degree murder charge that under Virginia law carries a potential sentence of five to 40 years in prison if convicted. It remains unresolved whether federal immigration authorities will seek to detain Cedillos-Campos for removal proceedings independent of the state criminal case, and whether any additional charges, including arson-related charges given the reported burning of the victim's body, will be filed.
