Armed illegal alien sentenced for operating Atlanta area methamphetamine laboratories

ATLANTA - Ramiro Contreras-Sandoval, an illegal alien from Mexico, will serve a 30-year prison sentence following his convictions for operating two conversion laboratories containing over 135 kilograms of liquid methamphetamine concealed in paint buckets and for possessing firearms as an illegal alien and in furtherance of his drug trafficking crimes. 

"This case should send a clear message to anyone thinking about running drugs or using deadly weapons to protect their operation: the federal government will relentlessly seek justice and protect the community from drug traffickers,” said U.S. Attorney Theodore S. Hertzberg. “The successful prosecutions of Contreras-Sandoval and his codefendant illustrate the positive impact collaboration among law enforcement agencies has on the community.”

“Operating methamphetamine labs is a reckless and dangerous crime,” said Jae W. Chung, Special Agent in Charge of the DEA Atlanta Division.  “This conviction underscores that DEA will aggressively pursue anyone who engages in drug trafficking activities that put lives at risk.”

According to U.S. Attorney Hertzberg, the charges, and other information presented in court: Between March 2019 and October 2021, Contreras-Sandoval and Genaro Davalos-Pulido operated two separate clandestine liquid methamphetamine conversion laboratories in the Atlanta area. On April 23, 2019, law enforcement seized over 135 kilograms of a methamphetamine mixture concealed in paint buckets that Contreras-Sandoval and Davalos-Pulido removed from the Morrow, Georgia conversion lab and attempted to transport in a vehicle driven by a conspirator. After law enforcement stopped the drug-laden vehicle, both Contreras-Sandoval and Davalos-Pulido fled the jurisdiction to avoid arrest. 

In the fall of 2021, agents located Contreras-Sandoval and Davalos-Pulido back in the Atlanta area – this time in a Norcross, Georgia neighborhood. On October 21, 2021, agents searched a Norcross residence and found Davalos-Pulido inside with a full-scale liquid methamphetamine conversion operation, a loaded Baretta handgun, $84,000 in cash, and a .50 caliber rifle that appeared ready to be shipped to Mexico. Agents arrested Contreras-Sandoval nearby and found approximately $12,000 in his vehicle and pockets. 

In June 2024, Davalos-Pulido pled guilty to conspiracy to possess with intent to distribute methamphetamine and possession of a firearm in furtherance of a drug trafficking crime. Davalos-Pulido was sentenced to 20 years in federal prison in October 2024.

Earlier today, U.S. District Judge Eleanor L. Ross sentenced Contreras-Sandoval, a/k/a Manuel Santiago Vazquez, a/k/a Jorge Gomez-Sandoval, a/k/a Mirin, 41, of Michoacán, Mexico, to 30 years in prison, to be followed by five years of supervised release. Contreras-Sandoval was convicted by a federal jury on September 16, 2025, of conspiracy to possess with intent to distribute methamphetamine, distribution of methamphetamine, possession with intent to distribute methamphetamine, possession of a firearm in furtherance of a drug trafficking crime, and possession of firearms by an alien illegally present in the United States.  

This case was investigated by the Drug Enforcement Administration and the Federal Bureau of Investigation, with valuable assistance provided by the Georgia Bureau of Investigation, Georgia State Patrol, Lawrenceville Police Department, Clayton County Police Department, and the Long Beach, California Police Department.

Assistant U.S. Attorneys Bethany L. Rupert and Thomas M. Forsyth, III prosecuted the case.

This case was part of Operation Take Back America, a nationwide initiative that marshals the full resources of the Department of Justice to repel the invasion of illegal immigration, achieve the total elimination of cartels and transnational criminal organizations, and protect our communities from the perpetrators of violent crime. Operation Take Back America streamlines efforts and resources from the Department’s Organized Crime Drug Enforcement Task Forces and Project Safe Neighborhood.

This case was also part of the Homeland Security Task Force (HSTF) initiative established by Executive Order 14159, Protecting the American People Against Invasion. The HSTF is a whole-of-government partnership dedicated to eliminating criminal cartels, foreign gangs, transnational criminal organizations, and human smuggling and trafficking rings operating in the United States and abroad. Through historic interagency collaboration, the HSTF directs the full might of United States law enforcement towards identifying, investigating, and prosecuting the full spectrum of crimes committed by these organizations, which have long fueled violence and instability within our borders. In performing this work, the HSTF places special emphasis on investigating and prosecuting those engaged in child trafficking or other crimes involving children. The HSTF further utilizes all available tools to prosecute and remove the most violent criminal aliens from the United States. HSTF Atlanta comprises agents and officers from ATF, CGIS, DEA, FBI, ICE-HSI, IRS-CI, DOL-OIG, DSS, USMS, USPIS, and USSS, as well as numerous state and local agencies, with the prosecution being led by the United States Attorney’s Office for the Northern District of Georgia.
