News Release, U.S. Attorney's Office, District of Hawaii, Friday, February 27, 2026

HONOLULU – United States Attorney Ken Sorenson announced that Douglas Neddles Keikilani Junior Manago, 46, of Ewa Beach, was sentenced on February 24, 2026, in federal court by Senior United States District Judge Helen Gillmor to 178 months in prison followed by 5 years of supervised release for possessing methamphetamine and a firearm after having been previously convicted of a felony.  Manago pled guilty pursuant to a plea agreement in November 2025.  He was remanded into custody following his sentencing.

According to court records, Manago was distributing methamphetamine on Oahu.  The charges to which he pled guilty stem from two separate traffic stops and subsequent search warrants executed on vehicles Manago was driving.  Manago admitted that he possessed methamphetamine intending to distribute it to others, as well as a firearm that he was prohibited from possessing due to a prior felony conviction.  In total, Manago was held responsible for over three pounds of methamphetamine.

The FBI and Honolulu Police Department investigated the case.

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.

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 comprises agents and officers from ICE-HSI, FBI, ATF, CBP, CGIS, DCIS, DEA, DSS, IRS-CI, NCIS, USMS, USPIS and HHIDTA with the prosecution being led by the United States Attorney’s Office for the District of Hawaii.
