Seventeen individuals accused of drug trafficking are now facing serious charges following allegations of operating an extensive methamphetamine network that dispersed hundreds of pounds of the substance each month throughout Northern California.

Placer County prosecutors revealed on Thursday that these suspects have been charged with offenses such as conspiracy and transporting large quantities of methamphetamine for sale. This comes after an intensive eight-month undercover investigation known as “Operation Meltdown.”

The probe was initiated in July 2025 when an undercover detective successfully purchased several pounds of meth from an alleged dealer in North Auburn, as reported by the Placer County Sheriff’s Office. What initially appeared as an isolated case rapidly expanded into what officials are calling a significant drug trafficking operation based in Sacramento, which supplied meth to Placer County.

Authorities estimate that the network was responsible for distributing around 500 pounds of methamphetamine monthly across Sacramento and Placer counties.

In a massive action on March 12, nearly two dozen law enforcement agencies coordinated efforts to raid 25 homes and locations across the region. This sweeping operation resulted in the arrest of multiple suspects, who were then taken to the Placer County Jail.

During these raids, investigators reported seizing 65 pounds of meth, over 7 kilograms of cocaine, approximately half a pound of MDMA, 26 firearms, more than $100,000 in cash, and what was identified as a DMT lab.

Sheriff’s officials say some members of the alleged ring had ties to a Mexican drug trafficking organization and Sacramento-area drug and gun trafficking gangs.

All 17 defendants have appeared in court and pleaded not guilty, prosecutors said.
