A nearly four-year narcotics investigation that dismantled multiple drug trafficking networks across Louisiana's bayou region has officially concluded, with federal and local authorities announcing 38 prosecutions and more than 300 combined years of prison sentences handed down against convicted defendants. Law enforcement agencies seized substantial quantities of drugs, firearms, cash, and other criminal assets over the course of the operation, which targeted distribution rings supplying Thibodaux, Lafourche Parish, and surrounding communities.
U.S. Attorney David I. Courcelle announced the conclusion of the operation on October 16, as reported by Tampa Free Press, with the Drug Enforcement Administration leading a multi-agency effort carried out under the Homeland Security Task Force — Region 15 CORE — New Orleans. According to the U.S. Department of Justice, that task force operates as a whole-of-government partnership uniting federal agencies and local prosecutors against transnational criminal organizations, violent gangs, and drug cartels. The coalition behind the Louisiana effort combined the DEA, FBI, ATF, and U.S. Border Patrol with the Louisiana State Police, the Thibodaux Police Department, and sheriff's offices from Lafourche, Terrebonne, and St. Charles parishes.
Investigation Began in 2022
The roots of the case stretch back to 2022, when a multiagency investigation began, with suppliers in Texas and California. A Thibodaux Police Department narcotics agent headed the field investigation, serving as a task force officer within the Eastern District of Louisiana's financial investigations unit, per Tampa Free Press. Federal prosecutors ultimately indicted 20 individuals on narcotics, firearms, and conspiracy charges, while state prosecutors in Terrebonne and Lafourche parishes brought cases against 18 more people.
Court filings kept coming right up to the public announcement. On October 9, Emmanuel Gomez-Mayorga was federally charged with conspiracy to possess with intent to distribute methamphetamine, the Justice Department reported — a sign that legal proceedings remained active even as officials touted the operation's conclusion. Several defendants, including Earl Henry Jr., are still awaiting sentencing or trial outcomes, per Tampa Free Press.
A 15-Year Sentence Among Dozens Handed Down
One defendant received 15 years — 180 months — in federal prison. That sentence sits in the middle of a long list of penalties the task force's work produced: 42-year-old Delvin Edmond and 44-year-old John Paul Gage Jr. each received 262 months for trafficking methamphetamine, fentanyl, and cocaine, the heaviest terms disclosed in the case, per Tampa Free Press.
Other sentences ranged widely depending on each defendant's role. Lionel Antoine Duncan received 180 months, Percy Howard got 160 months, and Faustin Williams and Andre Lee each received 151 months, according to Tampa Free Press. Leroy Otero was sentenced to 135 months, while Khillun Cheatham and Torrez Drane each received 120 months. Several other federal defendants received sentences ranging from 12 to 108 months, including Roy Robinson and Yolanda Tillman at 108 months, Justin Heims at 97 months, Linez Green at 66 months, Michael Lewis at 48 months, Rydelle Rounds at 24 months, James Williams at 15 months, and Anjhaelyn Haynes at 12 months. Tammy Thompson received supervised probation for misprision of a felony, per the same outlet.
Tillman's case had already drawn local attention. The Des Allemands woman was sentenced in May 2025 to nine years in federal prison after pleading guilty to conspiring to distribute cocaine and using her bank account to move money for traffickers and couriers in a network spanning Houston and Thibodaux, as Hoodline previously reported.
Drugs, Guns and Cash Pulled Off the Streets
The scale of what investigators recovered underscores how deeply the trafficking networks had embedded themselves in the region. Officers confiscated more than 100 pounds of crystal methamphetamine — 46,909.33 grams — along with roughly three pounds of cocaine, 6.5 pounds of marijuana, and 178.6 grams of heroin and fentanyl, according to Tampa Free Press. Eleven firearms, including eight pistols and three rifles, were also seized, alongside cash and criminal assets valued at more than $190,000 in total.
Federal court sentences across the case ranged from probation to more than 21 years in prison, with Delvin Edmond and John Paul Gage Jr. each receiving 262 months. Under 21 U.S.C. § 841, convictions for conspiracy to distribute 500 grams or more of a methamphetamine mixture, or 50 grams of pure methamphetamine, carry mandatory minimum sentences of 10 years and maximum terms of life imprisonment.
Officials Frame the Case as a Model for Rural Task Forces
Courcelle said the task force operation aims to protect communities from the violence posed by drug trafficking organizations, according to Tampa Free Press. John P. Scott said the investigation began with local police officers and deputies before expanding into a full Homeland Security Task Force operation, adding that federal operations now reach into rural communities and parish neighborhoods that might otherwise be overlooked.
Bryan Zeringue said the effort focused on cutting trafficking networks off at the supply level, arguing that arrests, firearm seizures, the removal of trafficking proceeds, and taking major distributors out of operation make the community safer. Craig Webre said the interagency work removed dangerous drugs and firearms from circulation and disrupted criminal organizations operating across parish lines. Louisiana State Police representative Frank Besson said the agency will continue working with partners to bring drug traffickers to justice wherever they operate, while Timothy Soignet said public safety efforts at this scale require a team of professionals working together.
