Final Defendant Sentenced in National Methamphetamine & Cocaine Trafficking Conspiracy

GRAND RAPIDS – Acting U.S. Attorney for the Western District of Michigan Alexis M. Sanford today announced that United States District Judge Jane M. Beckering sentenced Merria Wallace, 42, a resident of West Park, Florida with significant ties to Lansing, Michigan, to serve 120 months in prison for her role in a multi-state drug trafficking conspiracy. During sentencing, Judge Beckering characterized Wallace as a facilitator for a major drug trafficking organization, finding that she “was a really important part of this operation” – an operation responsible for distributing significant quantities of methamphetamine and cocaine throughout Michigan. Wallace is the final defendant to be sentenced in the case.

Wallace was the logistics manager for a conspiracy designed to import methamphetamine and cocaine to Michigan for sale. In her role, Wallace tracked packages containing approximately ten kilograms of methamphetamine sent to Michigan from California. She also booked flights for co-conspirators to fly thousands of dollars in drug proceeds to California and then return to Michigan with drugs, including cocaine. On multiple occasions, Wallace even traveled herself, transporting drug money on behalf of one of the conspiracy’s leaders, Jason Demyers. Overall, the organization distributed kilograms of cocaine and methamphetamine in and around Detroit, Lansing, and Kalamazoo between August 2022 and July 2024.

“The sentences in this case are significant and effectively hampered this transnational drug trafficking organization, which spanned multiple states, including Michigan, Florida, Arizona and California,” said Acting U.S. Attorney Alexis Sanford. “Our office is committed to combatting these organizations, including sources of supply from other states or countries who are responsible for distributing significant quantities of drugs into our West Michigan communities. We will continue to work with our federal, state, and local law enforcement partners to make our communities safer for everyone.”

During the investigation, law enforcement seized approximately ten kilograms of methamphetamine, eight kilograms of cocaine, multiple pieces of real property used to facilitate the drug trafficking conspiracy, and jewelry valued at approximately $325,000 that constituted proceeds of the drug trafficking conspiracy.

In total, the United States charged fourteen defendants as part of the organization. Twelve of the defendants have pleaded guilty, while two have entered a pretrial diversion program. The Court has imposed the following prison sentences on the convicted defendants:

The Drug Enforcement Administration (DEA) and the Lansing Police Department (LPD) began the investigation into Demyers’ drug trafficking organization in October 2022, in partnership with Internal Revenue Service Criminal Investigation (IRS-CI) and the Kalamazoo County Sheriff’s Office.

“The results of this investigation highlight the relentless work the Drug Enforcement Administration and our state and local partners do daily to keep our communities safe, said DEA Acting Special Agent in Charge Andrew P. Lawton. “With the assistance of the Lansing Police Department and the Michigan State Police, we have succeeded in holding those accountable for flooding our backyards with drugs and weapons. We will continue to prioritize the Mission of the Drug Enforcement Administration and bring those responsible for these crimes to justice. These severe sentences show that narcotics trafficking has grave consequences and should serve as a warning to the cartels and drug gangs alike.”

This prosecution, dubbed Operation Cold as Ice, was part of an Organized Crime Drug Enforcement Task Forces (OCDETF) investigation. OCDETF identifies, disrupts, and dismantles the highest-level drug traffickers, money launderers, gangs, and transnational criminal organizations that threaten the United States by using a prosecutor-led, intelligence-driven, multi-agency approach that leverages the strengths of federal, state, and local law enforcement agencies against criminal networks.

Assistant United States Attorneys Stephanie M. Carowan and Austin J. Hakes prosecuted the case on behalf of the United States.
