Douglas Neddles Keikilani Junior Manago, a 46-year-old resident of Ewa Beach, was sentenced to 178 months in federal prison and five years of supervised release for possessing methamphetamine and a firearm as a convicted felon. The sentencing took place on February 24, 2026, before Senior United States District Judge Helen Gillmor in Honolulu. Manago had pleaded guilty in November 2025 under a plea agreement and was taken into custody after the hearing.
Court records show that Manago was involved in distributing methamphetamine on Oahu. The charges were based on two separate traffic stops and subsequent searches of vehicles he was driving. During these incidents, Manago admitted to possessing methamphetamine with the intent to distribute and having a firearm despite being prohibited due to a prior felony conviction. Authorities held him responsible for more than three pounds of methamphetamine.
The case was investigated by the FBI and the Honolulu Police Department. Assistant U.S. Attorney Margaret C. Nammar prosecuted the case.
“This prosecution was part of the Homeland Security Task Force (HSTF) initiative established by Executive Order 14159, Protecting the American People Against Invasion,” according to the U.S. Attorney’s Office announcement. “The HSTF is a whole-of-government partnership dedicated to eliminating criminal cartels, foreign gangs, transnational criminal organizations, and human smuggling and trafficking rings operating in the United States and abroad. Through historic interagency collaboration, the HSTF directs the full might of United States law enforcement towards identifying, investigating, and prosecuting the full spectrum of crimes committed by these organizations, which have long fueled violence and instability within our borders. In performing this work, the HSTF places special emphasis on investigating and prosecuting those engaged in child trafficking or other crimes involving children. The HSTF further utilizes all available tools to prosecute and remove the most violent criminal aliens from the United States.”
HSTF Hawaii includes agents from multiple federal agencies such as ICE-HSI, FBI, ATF, CBP, CGIS, DCIS, DEA, DSS, IRS-CI, NCIS, USMS, USPIS and HHIDTA. Prosecution is led by the United States Attorney’s Office for the District of Hawaii.
