Gabriel Lebron Mejia, Drug Trafficking, Wisconsin 2026

MADISON, WIS. – In a shocking case of widespread drug trafficking, a Beloit man has been sentenced to a decade in prison. Gabriel Lebron Mejia, 27, was handed the 10-year sentence by Chief U.S. District Judge James D. Peterson on March 13, 2026, for possessing 100 grams or more of heroin intended for distribution and maintaining a drug trafficking premises.

The investigation, conducted by the FBI, the U.S. Drug Enforcement Administration, the ATF Madison Crime Gun Task Force, the Rock County Sheriff’s Office, and the City of Beloit Police Department, revealed that Mejia was a high-level drug trafficker. Between January and August 2025, law enforcement conducted controlled purchases of heroin and fentanyl from Mejia. During his subsequent arrest on August 28, 2025, officers searched Mejia’s vehicle and found a hidden compartment behind the vehicle’s glove box.

Inside, officers recovered 115 grams of a mixture containing heroin and fentanyl and 60 grams of cocaine. Officers also searched Mejia’s apartment and recovered 100 grams of fentanyl pills, a hydraulic pill press, a gas mask, cutting agents, and other tools and drug packaging material. Police also found a 9mm handgun, ammunition, and over $21,000 in cash.

At sentencing, Judge Peterson noted that the chemical makeup of the fentanyl that Mejia distributed raised a public safety concern about whether conventional overdose reversing treatments would be effective. Rock County District Attorney Jason Sanders joined U.S. Attorney Chadwick M. Elgersma in praising the federal, state, and local law enforcement officers who worked together to bring Mejia to justice.

“I am grateful for the collaboration between Rock County and the U.S. Attorney’s Office in this case,” said District Attorney Sanders. “I am proud that we were able to work together to secure a significant sentence against a large-scale drug trafficker.”

The charges against Mejia were the result of an investigation conducted by the FBI, the U.S. Drug Enforcement Administration, the ATF Madison Crime Gun Task Force, the Rock County Sheriff’s Office, and the City of Beloit Police Department. The ATF Madison Crime Gun Task Force is comprised of federal agents with ATF and Task Force Officers from state and local agencies throughout the Western District of Wisconsin.

Operation Take Back America is a nationwide initiative that marshals the full resources of the Attorney’s Office 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.

Mejia pleaded guilty to the charges on March 13, 2026. The investigation revealed that Mejia was a high-level drug trafficker who was involved in the distribution of over 200 grams of heroin and fentanyl. He was found with a 9mm handgun and over $21,000 in cash. The sentence is a significant blow to Mejia and his operation.
