Former Fort Myers Resident Sentenced to Federal Prison for His Role in Firearm Trafficking Scheme (DOJ)

Fort Myers, FL - Osnyson Desrosiers (Atlanta, Georgia), formerly of Fort Myers, has been sentenced by U.S. District Judge Kyle Dudek to two years in federal prison for his role in a firearm trafficking scheme. Desrosiers pleaded guilty on November 19, 2025, to conspiring to make a false statement to a firearms dealer and making false statements to a firearms dealer. U.S. Attorney Gregory W. Kehoe made the announcement.

According to court records, in early-to-mid 2022, Desrosiers and his co-defendant, Derick Desir, collaborated to "straw purchase" several dozen Glock handguns from licensed firearms dealers in Florida. While making these firearm purchases, they falsely represented to each firearm dealer that they were the "actual buyer or transferee" of the firearms, even though they knew that the firearms they were purchasing were being unlawfully trafficked to a third party. Evidence uncovered by investigators revealed that these firearms were later smuggled into Canada, where several have since been recovered during various Canadian law enforcement investigations.

In November 2025, Desir was sentenced to 3 years and 10 months in federal prison for his role in the conspiracy.

This case was investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives and Homeland Security Investigations. It was prosecuted by Assistant United States Attorney Simon Eth.

This case is part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations (TCOs), and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department's Organized Crime Drug Enforcement Task Forces (OCDETFs) and Project Safe Neighborhood (PSN).
