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 methamphetamine trafficking and illegal firearm possession. The sentencing took place on February 24, 2026, before Senior United States District Judge Helen Gillmor in Honolulu. Manago had previously pleaded guilty in November 2025 under a plea agreement and was taken into custody after the sentencing.
Court records indicate that Manago distributed methamphetamine on Oahu. The charges resulted from two separate traffic stops and subsequent searches of vehicles he was driving. He admitted to possessing methamphetamine with the intent to distribute and having a firearm despite being prohibited due to an earlier felony conviction. Authorities held him responsible for more than three pounds of methamphetamine.
The Federal Bureau of Investigation (FBI) and the Honolulu Police Department conducted the investigation. Assistant U.S. Attorney Margaret C. Nammar prosecuted the case.
According to the U.S. Attorney’s Office, "This prosecution was part of the Homeland Security Task Force (HSTF) initiative established by Executive Order 14159, Protecting the American People Against Invasion." The statement continued: "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."
The Hawaii branch of HSTF includes agents from multiple federal agencies such as ICE-HSI, FBI, ATF, CBP, CGIS, DCIS, DEA, DSS, IRS-CI, NCIS, USMS, USPIS as well as HHIDTA; prosecutions are led by the U.S. Attorney’s Office for Hawaii.
