ATLANTA, GA — A 22-year-old Mexican national was arrested in Clayton County for selling purple fentanyl, a potent and dangerous variant of the synthetic opioid, federal authorities said.
Martin Armando Gonzalez-Martinez, of Oaxaca, Mexico, appeared last week before a U.S. magistrate judge, facing possession with intent to distribute fentanyl.
According to U.S. Attorney Theodore S. Hertzberg, Gonzalez-Martinez illegally crossed the U.S. southwest border several years ago and allegedly collaborated with Mexico-based traffickers to distribute fentanyl in the Atlanta area.
On March 4, law enforcement apprehended Gonzalez-Martinez in Morrow, Georgia, after he was observed selling drugs from a backpack in a business parking lot. The Drug Enforcement Administration (DEA) seized four kilograms of suspected purple fentanyl during the arrest.
“Fentanyl is so extremely dangerous that just a couple of milligrams can be lethal,” Hertzberg said. He emphasized the office’s commitment to identifying, arresting, and prosecuting individuals responsible for trafficking the deadly drug, which contributes to tens of thousands of deaths annually in the U.S.
Jae W. Chung explained that purple fentanyl is a particularly serious threat. “Traffickers continue to push dangerous and deceptive products into our communities. Purple fentanyl often contains carfentanil or xylazine, making it even more lethal than traditional fentanyl,” Chung said.
Authorities noted that purple coloring is sometimes used as a branding tool to differentiate fentanyl from other white powders such as cocaine or heroin. However, dyed variants may contain extremely potent additives, including carfentanil—100 times stronger than fentanyl—and xylazine, a veterinary sedative that does not respond to Narcan.
The DEA’s 2025 National Drug Threat Assessment also warns that purple fentanyl can contain “benzo-dope,” which prolongs sedation even after breathing is restored following an overdose.
Federal authorities have not confirmed whether the seized fentanyl contained these additives. Gonzalez-Martinez remains in federal custody as investigations continue.
