An extensive drug investigation that targeted a drug trafficking network operating in Louisiana and California has resulted in the seizure of 20 pounds of methamphetamine and eight pounds of marijuana, and led to the indictment of seven Baton Rouge residents and two other people.

The high-grade methamphetamine alone, seized as part of Operation Armageddon, has a street value of more than $1 million, said U.S. Attorney Walt Green. He said the methamphetamine seizure is the largest in the history of the East Baton Rouge Parish Sheriff’s Office.

“We are proud to be part of the combined efforts of all of the participating agencies in the task force,” East Baton Rouge Parish Sheriff Sid Gautreaux said. “I am extremely proud of my deputies and the contributions that they were able to make on a case of such magnitude.”

In addition to the drugs, agents seized a number of guns, including an AR-15 semi-automatic rifle, Green said.

“We will continue to meet the threat posed by drug trafficking organizations by working tirelessly with our excellent federal, state and local partners to aggressively pursue drug dealers,” Green said.

The Baton Rouge defendants are Oscar Machado-Galeana, 32; Alexander P. Nava, 45; Lori Lee Landry, 39; Devin Joel Martin, 25; Gregory John Landry, 39; Roy Martin Herrera Romero, 38; and Mervin Ronald Spencer, 24.

The other defendants are Victor Hugo Sandoval-Quinonez, 36, of Breaux Bridge; and Marco Antonio Lopez-Sandoval, 20, of California.

All nine people are charged with conspiracy to distribute and possess with the intent to distribute methamphetamine, heroin and marijuana.

In addition, Machado-Galeana and Nava face several other drug charges as well as money-laundering conspiracy and firearms charges.

Lopez-Sandoval is also charged with money-laundering conspiracy counts.

The operation is being handled by the U.S. Attorney’s Office; Drug Enforcement Administration; the sheriff’s offices in East and West Baton Rouge and Ascension parishes; Baton Rouge Police Department; Internal Revenue Service — Criminal Investigations; U.S. Department of Homeland Security; and Bureau of Alcohol, Tobacco, Firearms and Explosives.
