U.S. Immigration and Customs Enforcement (ICE) in Buffalo has announced the arrest of a 55-year-old Salvadoran national previously convicted of murder, assault, and weapons offenses in New York. This action is part of its “Worst of the Worst” enforcement initiative.
According to ICE–Buffalo, on November 14, officers arrested Valentin Argueta, a Salvadoran national identified as a violent criminal alien. The “Worst of the Worst” summary indicates that Argueta was convicted in Nassau County, New York, for murder, assault, and criminal possession of a weapon, receiving a 25-years-to-life sentence. After his incarceration, ICE Enforcement and Removal Operations took custody to initiate immigration proceedings for his removal from the United States. The case highlights how the initiative targets foreign nationals with serious violent histories—particularly those involved in homicide and armed attacks that threaten public safety.
ICE Enforcement and Removal Operations reports that in recent fiscal years thousands of noncitizens with convictions for homicide, manslaughter, or serious assault have been arrested for removal. An increasing share is flagged under initiatives like “Worst of the Worst.” These programs allocate federal resources toward the most dangerous offenders, often individuals serving long sentences for murder or attempted murder who are transferred directly from state prisons into immigration custody. By prioritizing these cases, ICE aims to ensure that once violent foreign offenders complete their sentences, they face removal proceedings rather than being released back into U.S. communities.
New York State crime data show that murder and nonnegligent manslaughter cases account for a disproportionate share of public concern and law enforcement resources despite being a small fraction of total offenses. Particularly in downstate counties like Nassau, many homicide prosecutions involve firearms and repeat violent offenders leading to lengthy sentences similar to Argueta’s 25-years-to-life term. State officials increasingly collaborate with federal partners such as ICE to identify noncitizen offenders so they can be transferred into federal custody upon completing their terms instead of being released outright.
U.S. Immigration and Customs Enforcement (ICE), established in 2003 and headquartered in Washington D.C., is an agency within the Department of Homeland Security responsible for interior immigration enforcement and combating transnational crime. Its Enforcement and Removal Operations division focuses on identifying, arresting, detaining, and removing noncitizens who violate immigration law with an emphasis on those convicted of serious crimes such as murder, sexual assault, and major drug offenses. The Buffalo Field Office oversees enforcement in upstate New York and parts of Pennsylvania by working with local law enforcement and state prisons to take custody of offenders like Argueta as they finish their sentences while prioritizing “Worst of the Worst” cases.
