A Greenwich resident is at the center of a major Westchester sting after prosecutors say a multi-agency operation turned up roughly two dozen illegal guns and a stash of cocaine. Investigators say they recovered 22 ghost guns, three serialized firearms, multiple high-capacity magazines and about six ounces of cocaine, a haul announced this week by county prosecutors and their federal partners.
According to FBI New York, the takedown was part of "Operation Summer Heat 2.0" and involved the bureau's Westchester Safe Streets Task Force, Homeland Security Investigations and local police agencies. The FBI said the operation led to the recovery of large-capacity magazines and three serialized firearms and framed the case as part of a broader push to get illegal guns and drugs off neighborhood streets.

What investigators recovered
In a statement outlining what they say they pulled from the operation, prosecutors listed 22 unserialized ghost guns, including two assault-style rifles, along with three serialized firearms, multiple large-capacity magazines and roughly six ounces of cocaine, according to News 12. Ghost guns, which lack serial numbers and can be built from unfinished parts or 3D-printed components, are notoriously difficult for law enforcement to trace. Officials did not say whether any of the seized weapons have been linked to earlier shootings.
The arrest and charges
Greenwich resident Michael Larriuz, 49, was arrested in White Plains and charged with first-degree criminal sale of a controlled substance, first-degree criminal sale of a firearm and five counts of third-degree criminal sale of a controlled substance, the Westchester County District Attorney's Office said in a statement cited by Greenwich Time. Larriuz was arraigned last week, where a judge set bail at $100,000 cash, $250,000 bond or $500,000 partially secured bond. Prosecutors say the charges are tied to both the alleged weapons dealing and the amount of drugs recovered in the sting.
How authorities say the sting worked
Local outlets report that the arrest capped a months‑long undercover probe by the DA's Criminal Investigators Squad. During that time, Larriuz allegedly sold guns and drugs to a confidential informant on roughly 10 occasions between mid‑December and late May, including some deals that reportedly went down at a Mobil gas station on the Harrison–White Plains line, according to Daily Voice. Prosecutors say the investigation came to a head with Larriuz's mid‑June arrest, followed by searches and seizures tied to the case. Officials have not disclosed where the weapons and drugs were ultimately found.
Prosecutors and feds weigh in
Westchester County District Attorney Susan Cacace credited the coordinated work across agencies, while the FBI highlighted the larger public-safety goals behind the operation. "The arrest of Michael Larriuz on both drug and illegal gun charges is a clear example of the dangerous criminal activity these joint enforcement efforts are designed to disrupt," FBI New York Assistant Director in Charge James C. Barnacle Jr. said in a statement reported by Greenwich Time. The DA's office also pointed to a countywide rise in ghost-gun recoveries last year as part of what is driving sting efforts like this one.
Legal stakes and next steps
Under New York law, criminal sale of a controlled substance in the first degree is a class A‑I felony, as set out in New York Penal Law §220.43 on the New York State Senate website. Larriuz was arraigned in White Plains with bail set as described in local reporting, and prosecutors say the investigation is still active. The DA's office and federal partners have asked anyone with information about the case to contact authorities, according to NBC Connecticut.
