Hartwick is the husband of Magana-Zavala. All six defendants were indicted by a federal grand jury in the summer of 2021. Oscar Madrigal pleaded guilty on April 4, 2022; Rosa Madrigal pleaded guilty on May 25, 2022; William Hartwick pleaded guilty on August 30, 2022; and Maria Magana-Zavala pleaded guilty on October 4, 2022. Salvador Magana Madrigal and Anahi Plascencia Cardona were found guilty of conspiracy to distribute 500 grams or more of methamphetamine and conspiracy to commit money laundering following a four-day federal jury trial in Sioux Falls on May 2, 2023. The conviction stemmed from activities that started when Salvador Madrigal and Anahi Cardona, who are husband and wife, recruited other members of Madrigal's family to assist them in obtaining large amounts of methamphetamine from California and distributing it in Sioux Falls. Salvador Madrigal and Cardona recruited Madrigal's aunt and uncle, Maria Magana Zavala and William Hartwick, to transport methamphetamine by vehicle from California. Eventually, Salvador's brother Oscar became involved in the conspiracy by assisting his brother in transporting and counting shipments of methamphetamine. In total, they obtained and distributed over 150 pounds of methamphetamine and 100 pounds of marijuana throughout the duration of the conspiracy. Salvador Madrigal, Jr. and Cardona, along with Salvador's mother, Rosa Madrigal, also intentionally conspired to knowingly conduct wire/money transfers which involved the proceeds of unlawful activities. The group conducted numerous financial transactions intended to transfer the proceeds from methamphetamine sales while concealing the nature and ownership of the money. Agents believe the group laundered over $1,000,000 of drug proceeds. At the time of their arrest, Cardona and Madrigal had approximately $215,000 stored in the garage of their home. "This multidefendant conspiracy case is yet another example of the impactful work the U.S. Attorney's Office is doing alongside its law enforcement partners to dismantle drug organizations in South Dakota," said Alison J. Ramsdell, U.S. Attorney for the District of South Dakota. "We are especially grateful to our partners in the Sioux Falls Area Drug Task Force, the Drug Enforcement Administration, and the IRS-Criminal Investigations for their collaboration to bring down this family drug operation that brought more than 150 pounds of methamphetamine into our communities." "A 265-month sentence sends a strong message that trafficking drugs into our communities will not be tolerated," said IRS Criminal Investigation (CI) Assistant Special Agent in Charge Melissa McFadden, St. Louis Field Office. "When criminals launder their ill-gotten funds to hide the source of their crimes, the special agents of CI take pride in uncovering the money trail that leads to the source and helps put a stop to the drug trafficking operation." This case was investigated by the Internal Revenue Service Criminal Investigation (CI), Sioux Falls Area Drug Task Force, and the Drug Enforcement Administration. Assistant U.S. Attorney Mark Hodges prosecuted the case. All defendants were immediately remanded to the custody of the U.S. Marshals Service following their respective sentencings. CI is the criminal investigative arm of the IRS, responsible for conducting financial crime investigations, including tax fraud, narcotics trafficking, money-laundering, public corruption, healthcare fraud, identity theft and more. CI special agents are the only federal law enforcement agents with investigative jurisdiction over violations of the Internal Revenue Code, obtaining a more than a 90 percent federal conviction rate.
