Cartel-Linked Drug Trafficker Sentenced as Operation Sweet Silence Dismantles Violent Network
COLUMBUS, Ga. — A member of the Sinaloa Cartel has been sentenced to more than 11 years in federal prison as part of a sweeping investigation targeting gang violence and large-scale drug trafficking in the Columbus area.
Juan Carlos Torres-Arzapalo, 41, of Mexico, was sentenced to 135 months in prison after pleading guilty to drug conspiracy charges. He is expected to be deported following his sentence.
The case is part of Operation Sweet Silence, a multi-year investigation led by the Federal Bureau of Investigation and the Drug Enforcement Administration, targeting violent crime and drug trafficking tied to street gangs and cartel activity in the region.
According to investigators, the operation ran from August 2022 through May 2024 and focused on dismantling the Zohannon street gang and disrupting other criminal organizations, including US World, Crips, Bloods and Gangster Disciples, all of which had ties to Mexican drug cartels.
Authorities said Torres-Arzapalo worked alongside co-defendant Ulises Cervantes, a large-scale drug supplier with connections to the Sinaloa Cartel, to distribute methamphetamine, cocaine and marijuana throughout the Middle District of Georgia.
Wiretap evidence revealed discussions involving kilogram-level drug deals, including negotiations for as much as 50 kilograms of methamphetamine and large shipments of marijuana and cocaine.
During the investigation, agents documented drug deliveries, including a kilogram of cocaine delivered to a Columbus residence. Surveillance and intercepted communications helped build the case against multiple defendants.
The operation resulted in the seizure of an estimated $270 million worth of drugs, including fentanyl, methamphetamine, cocaine and marijuana. Authorities also recovered 119 firearms, including machine guns and stolen weapons, removing them from the streets.
In total, 31 defendants were charged across multiple indictments. So far, 30 have pleaded guilty or been convicted, with sentences ranging from probation to decades in prison.
The case was investigated by federal and local agencies, including the FBI, DEA and the Muscogee County Sheriff’s Office, with assistance from multiple regional partners.
Deputy Criminal Chief Veronica Hansis for the Middle District of Georgia and Trial Attorney Matthew Mattis with the Department of Justice’s Violent Crime and Racketeering Section are prosecuting the case.
Officials said the operation underscores the impact of coordinated law enforcement efforts aimed at dismantling violent criminal organizations and improving public safety.
