A California man who helped move a mountain of cocaine through the Baltimore area is headed to federal prison for just over a decade, after what prosecutors say was a late-summer sting that cracked open a major trafficking pipeline. Mario Valencia-Birruetta, 35, of Corning, California, was sentenced Friday in U.S. District Court to 121 months behind bars following an August 2023 operation that netted more than 100 kilograms of cocaine, multiple guns and equipment used to process bulk shipments, according to officials.
In a press release, the U.S. Attorney's Office for the District of Maryland said Valencia-Birruetta pleaded guilty to conspiracy to distribute cocaine and possession with intent to distribute. The office said the investigation pulled together teams from the Drug Enforcement Administration, Homeland Security Investigations and IRS-Criminal Investigation, with assistance from Baltimore City and Baltimore County police. Assistant U.S. Attorneys Calvin Miner and Stanton Lawyer handled the prosecution, according to the release.
How investigators tracked him
Court records reviewed by CBS Baltimore show Valencia-Birruetta popped onto law enforcement’s radar in mid-August 2023, when airlines flagged his travel and placed him on a flight watch list. From there, surveillance teams tailed him from BWI to a Hamilton Residence hotel in Baltimore, where agents watched a steady flow of suspected traffickers pay him visits. At one point, investigators saw him handling a large amount of cash before he headed to a bank, the records state. Teams later tracked meetings near National Harbor and followed the route back to a Timonium stash location that investigators were already watching.
Stash house seizure and what investigators found
When agents made their move on Aug. 30, 2023, they say they walked into a full-scale cocaine operation. According to the U.S. Attorney's Office, officers seized 43 individual kilogram packages from a vehicle tied to the case and another 32 kilogram packages from inside the Timonium stash spot. They also recovered a kilo press, quick cappers, digital scales, sifters, cash and three firearms. Prosecutors said the combined haul topped 100 kilograms of cocaine and formed the backbone of the federal case.
Legal fallout
Valencia-Birruetta was taken into custody during the stash-house operation and later appeared before U.S. District Judge James K. Bredar, who imposed the 121-month sentence on the conspiracy charge, officials said. Prosecutors framed the case as a textbook example of joint federal, state and local work and publicly thanked the agencies involved. The release did not offer additional details about other defendants, potential co-conspirators or any pending appeals.
