Massachusetts Man Pleads Guilty to Knowingly Concealing the Source of Material Support or Resources to ISIS

BOSTON - A Wakefield, Mass. man has pleaded guilty to knowingly concealing the source of material support or resources intended for the Islamic State of Iraq and al-Sham (ISIS).

Mateo Ventura, 20, pleaded guilty on Oct. 15, 2025 to one count of concealment of financing of terrorism. U.S. District Court Judge Denise Casper set sentencing for Jan. 8, 2026. Ventura was charged by complaint in June 2023 and was indicted by a federal grand jury in October 2023.

According to the charging documents, Ventura provided multiple gift cards to an individual he believed was an ISIS supporter, with the intention that they be sold on the dark web for a little less than face value, and with the profits being used to support ISIS. Ventura stated that he wanted the proceeds to go to ISIS "for war on kuffar," (disbelievers). In total between January and May 2023, Ventura made donations totaling $705.

The charge of attempting knowingly concealing the source of material support or resources to a foreign terrorist organization provides for a sentence of up to 10 years in prison, up to a lifetime of supervised release and a fine of up to $250,000. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.

United States Attorney Leah B. Foley; Assistant Attorney John A. Eisenberg for the Justice Department's National Security Division; and Ted E. Docks, Special Agent in Charge of the Federal Bureau of Investigation, Boston Division made the announcement today. Assistant U.S. Attorney Timothy H. Kistner of the National Security Unit is prosecuting the case. Valuable assistance was provided by Trial Attorney Michael Dittoe of the Justice Department's National Security Division.
