Officials claim Daby Jr. and Duncan are responsible for operating the largest drug trafficking organization throughout Guyana, relying on semi-familiar Narco submarines and aircraft to transport cocaine while bribing local government officials.

"All property and interests in the property and property of designated or blocked persons described in the United States are blocked and must be reported to OFAC," the Treasury Department said.
According to U.S. officials, sanctions came when authorities tried to crack down on homemade Narco submarines traveling through the jungles of Guyana while carrying record cocaine.

"Guyana is a close partner of the United States in combating narcotic trafficking," the Treasury said in a statement. "Nevertheless, corruption in Guyana poses a significant obstacle to efforts to combat drug trafficking, according to the 2025 International Bureau Local Narcotics Control Strategy Report."
