The Mexican duo have been sentenced to prison for distribution of methamphetamine and conspiracy to distribute methamphetamine in a counterfeit Adderall conspiracy investigated by the Homeland Security Task Force (HSTF) Washington, D.C., and HSTF Dallas.
According to court documents, Venancio Martinez Antero, 35, and Cesar Adan Rojo-Ortiz, 35, participated in a conspiracy that began at least as early as April 2019 and used darknet marketplaces to advertise and distribute counterfeit pills containing methamphetamine. Once orders were placed, co-conspirators sent customer names, shipping addresses, and drugs to redistributors such as Martinez Antero and Rojo-Ortiz who manufactured and packaged drugs for shipment and distribution nationwide.
Law enforcement seized over five kilograms of counterfeit Adderall pills (approximately 13,692 pills) associated with the conspiracy. Between September 2019 and July 2025, law enforcement made 47 controlled purchases from the conspirators’ darknet vendor accounts and accounts on encrypted messaging applications for up to 3,000 counterfeit Adderall pills at a time.
Law enforcement searched a garage that was controlled by Martinez Antero and Rojo-Ortiz and seized, among other items, $2,900, a blender, 2.8 kilograms of methamphetamine, an additional 12.5 kilograms of binding material, and an industrial pill press fitted with attachments to manufacture counterfeit Adderall pills.
Federal authorities said more than five kilograms of counterfeit Adderall pills were seized during the investigation.
Martinez Antero was sentenced to 11 years and three months in federal prison. Rojo-Ortiz was sentenced on Thursday, June 4, to seven years and six months in prison.
