Brazilian National Sentenced for Selling Firearms Without a License and Conspiracy

BOSTON - A Brazilian national unlawfully living in Massachusetts and New Hampshire was sentenced yesterday for dealing firearms without a license.

Riquelme Henrique De Aguiar Ferreira, a/k/a "Koringa," 22, was sentenced by U.S. District Judge William G. Young to two years in prison, to be followed by two years of supervised release. The defendant is subject to deportation proceedings upon completion of the imposed sentence. In September 2025, De Aguiar Ferreira pleaded guilty to one count of conspiracy to engage in the business of dealing firearms without a license and one count of engaging in the business of dealing firearms without a license.

Between May 2023 and August 2023, De Aguiar Ferreira coordinated the sale of two pistols (one with a large capacity magazine) to a cooperating witness without the required license in exchange for cash. The following year, De Aguiar Ferreira also offered the cooperating witness additional firearms for sale, but those transactions never occurred. De Aguiar Ferreira also conspired with others to deal firearms, traveling to South Carolina and connecting supply sources in South Carolina with individuals in Massachusetts. The picture below of the firearms obtained from South Carolina were found on De Aguiar Ferreira's phone:
