A 22-year-old Salvadoran migrant faces first- and second-degree murder charges after authorities say he fatally stabbed two women he knew, his coworker and his roommate, in separate attacks just hours apart on Long Island late last week.
Nassau County police took Rony Yahir Alvarenga Rivera into custody Saturday, one day after both women were found dead at two locations roughly two and a half hours apart. Nassau County Police Chief Patrick Ryder told reporters that both victims died from multiple stab wounds to the neck and torso, as Breitbart reported.
The first victim, 42-year-old Ana Maria del Aguila-Cordova, was a mother from Long Beach who worked alongside Rivera at a Wendy's restaurant in Island Park. Officers found her body outside the restaurant at approximately 12:30 a.m. Friday. Police said she had been taking out the garbage when she was attacked.
By 3:00 a.m. that same morning, officers discovered a second body, Rivera's 32-year-old roommate, who has not yet been publicly identified, inside an apartment building in Valley Stream. Authorities said Rivera knew both women.
The investigation moved quickly. The New York Post reported that Rivera himself contacted police, telling officers he had "killed somebody that night." Detective Lt. George Darienzo, commanding officer of the Nassau police homicide unit, relayed that account to reporters.
When pressed on what drove the attacks, Darienzo offered one word: "anger." He did not elaborate further. He also told NBC4 that Rivera has no known gang connection.
The charges filed against Rivera include one count of first-degree murder and two counts of second-degree murder, Fox News reported. He is expected in court Tuesday.
What remains unclear is the full motive. Police have described the killings as driven by anger but have not disclosed what sparked it. No charging documents or case numbers have been released publicly. The name of the 32-year-old roommate has not been made available. These gaps leave significant questions about what happened in the hours before two women lost their lives.
Nassau County Executive Bruce Blakeman, a Republican who is running against incumbent Gov. Kathy Hochul, wasted no time connecting the killings to immigration policy. Blakeman said Rivera entered the United States a decade ago as an unaccompanied 12-year-old from El Salvador.
Blakeman described a federal program he said allowed unaccompanied minors to remain in the country and eventually obtain legal status:
"In 2022, the federal government had a program where any unaccompanied minors that were in the United States automatically would receive papers that let them stay here legally in the form, I believe, of a green card."
It is worth noting that Blakeman's characterization of Rivera's immigration history has not been independently confirmed by documentary evidence in the public record so far. But his broader point, that lax enforcement allowed individuals to, in his words, "run around without any supervision whatsoever", speaks to a frustration shared by millions of Americans who have watched border policy deteriorate for years.
The pattern is not isolated. Across the country, communities have confronted cases where illegal immigrants face charges in violent crimes that raise hard questions about who was let in, who was tracked, and who fell through the cracks.
Blakeman was blunt in his assessment of the consequences. He told reporters:
"This didn't have to happen. This is a policy that has resulted today in two women being killed. They could've gone on to have very productive and happy lives. But they're no longer with us because of failed policies in the past."
Blakeman also used the press conference to highlight Nassau County's participation in the federal 287(g) program, a partnership that allows local police to perform limited immigration enforcement functions under ICE supervision. He said the program has enabled Nassau County to remove "over 2,000 illegal migrants with criminal records."
That number matters. It represents real cases, real criminal records, attached to individuals who were living in a single suburban county on Long Island. And Blakeman warned that the program's future is not secure. He said Gov. Hochul wants to abolish it.
The political stakes here are plain. On one side, local officials in places like Nassau County are using every available tool to identify and remove illegal immigrants with criminal histories. On the other, progressive leaders in Albany and Washington have spent years trying to limit cooperation between local law enforcement and federal immigration authorities. The debate over migrant protections and enforcement has played out repeatedly in Congress, with Democrats pushing to shield migrants from exactly the kind of accountability that programs like 287(g) are designed to enforce.
If Hochul succeeds in dismantling the program, Nassau County would lose a tool that Blakeman says has already removed thousands of criminal illegal immigrants from the community. The question voters will ask is simple: Why?
Ana Maria del Aguila-Cordova leaves behind two young children, ages one and eight. She was 42 years old. She was working a late shift at a fast-food restaurant. She walked outside to take out the trash and never came back in.
Her coworker, the man now charged with her murder, had worked alongside her at that same Wendy's. Whatever anger drove Rivera, it ended two lives in a span of hours and shattered a family.
The second victim, Rivera's 32-year-old roommate, remains unidentified publicly. Her story, her family, her circumstances, all of it is still emerging. What is known is that she was found dead in her own home, killed by someone she lived with.
These are the people who bear the cost when policy fails. Not the politicians who crafted the rules. Not the bureaucrats who processed the paperwork. Not the activists who demanded sanctuary protections. The cost falls on a mother of small children working the night shift, and on a young woman in her own apartment.
Meanwhile, some elected officials continue to push for policies that would make enforcement even harder. Proposals to offer reparations to illegal immigrants and prosecute enforcement officials represent the furthest extreme of a political movement that treats immigration enforcement itself as the problem, rather than the violence that enforcement is meant to prevent.
And when local prosecutors drop charges against those who assault officers enforcing immigration law, the message to communities like Nassau County is unmistakable: you're on your own.
Rivera is expected in court Tuesday. The charges, first- and second-degree murder, carry the possibility of life in prison under New York law. The investigation remains active, with the motive still officially described only as "anger" and the second victim still unidentified.
Open questions remain. What was Rivera's precise legal status at the time of the killings? What supervision, if any, was he under? Did any agency flag concerns about him in the decade since he arrived as an unaccompanied minor? And will the state of New York allow Nassau County to keep the tools it says are working?
Blakeman framed the stakes as clearly as anyone could. Two women are dead. A policy allowed the man charged with killing them to remain in the country for a decade. And the officials who enabled that policy have yet to answer for it.
Accountability doesn't start when the bodies are found. It starts when the border is open and nobody asks what happens next.
