In July 2019, James Rumbaua Damaso, recruited others to receive packages containing methamphetamine hydrochloride. The methamphetamine was mailed to Guam using the U.S. Postal System.  U.S. Postal Inspectors intercepted one of Damaso’s packages containing 1,783 net grams of methamphetamine hydrochloride that was analyzed with a purity of 97%.  He was arrested by officers with Homeland Security Investigations (HSI) and the U.S. Postal Inspection Service (USPIS).  Damaso was found with an additional 121.4 grams of methamphetamine hydrochloride, $31,418.00 in U.S. Currency, a drug scale and paraphernalia.

On November 23, 2021, James Rumbaua Damaso was found guilty after nine days of jury trial in the U.S. District Court of Guam. Damaso had prior convictions, including a serious drug felony, subjecting him to enhanced penalties. 

“This significant sentence is the result of productive teamwork by multiple agencies at all levels of government,” said John F. Tobon, Special Agent in Charge, HSI Honolulu. “HSI will continue to target individuals and organizations involved in transnational crime.” 

"This sentence is a reminder to drug traffickers that we will not tolerate using the U.S. mail to transport controlled substances in Guam or anywhere else," said Acting Inspector in Charge Kevin Rho of the U.S. Postal Inspection Service, San Francisco Division.  " I would like to thank local and federal law enforcement agencies for their partnership in stopping the spread of drugs this defendant to justice."
