HONOLULU – United States Attorney Ken Sorenson announced that four individuals from Oahu were sentenced this week in federal court by Senior United States District Judge J. Michael Seabright for their roles in a tax refund fraud scheme following their convictions by a federal jury on August 27, 2025.

Rosemarie Lastimado-Dradi, formerly of Kapolei, was sentenced to 108 months in prison for conspiring to defraud the United States, aiding in the preparation or filing of false tax returns, and money laundering. Marciaminajuanequita Dumlao of Honolulu was sentenced to 33 months in prison for conspiring to defraud the United States, money laundering, and making a false statement under oath in a bankruptcy proceeding. Finally, married couple Elvah Miranda and Daniel Miranda of Waipahu, were sentenced to 48 months and 30 months in prison, respectively. Elvah Miranda was convicted of conspiring to defraud the United States, filing a false tax return, and money laundering. Daniel Miranda was convicted of conspiring to defraud the United States and making a false statement under oath in a bankruptcy proceeding. All four defendants were also sentenced to 3 years of supervised release and ordered to pay restitution.

According to court documents and evidence presented at trial, from at least January 2015 through September 2018, the defendants conspired to defraud the Internal Revenue Service (IRS). As part of their tax refund fraud scheme, the defendants filed fraudulent individual tax returns and other tax documents that reported false withholdings from mortgage lenders and then claimed substantial refunds from the IRS. After processing the false returns, the IRS issued refunds to Dumlao and the Mirandas totaling over $1 million. The defendants created trusts, opened new bank accounts in the names of business entities and the trusts, and transferred the criminal proceeds between the accounts to conceal the funds from the IRS. Lastimado-Dradi, Dumlao, and Elvah Miranda laundered the fraudulently obtained refunds through a series of bank transactions.

The defendants also engaged in conduct to obstruct IRS efforts to recover the fraudulently obtained refund money, including sending frivolous correspondence to the IRS, filing retaliatory liens against the IRS employee assigned to recover the fraudulently obtained funds, and filing for bankruptcy. Dumlao and Daniel Miranda each filed for bankruptcy and made false statements under oath in relation to their respective bankruptcy proceedings. Lastimado-Dradi successfully promoted the tax fraud scheme to at least five participants in the District of Hawaii, which caused a total tax loss of at least $2,122,837.24. In exchange for her assistance promoting the fraud scheme and obstructing IRS collection efforts, Lastimado-Dradi received a cut of the fraud proceeds totaling approximately $998,261.

In sentencing Lastimado-Dradi to a term of imprisonment of nine years, Judge Seabright called Lastimado-Dradi the “mastermind of the scheme in Hawaii” and said that “her fingerprints are just everywhere in this scheme.”

In addition to the term of imprisonment, Judge Seabright ordered Lastimado-Dradi to pay $1,724,503.94 in restitution to the United States, Dumlao to pay $325,981.86 in restitution, and both Elvah and Daniel Miranda to jointly and severally pay $567,789.55 in restitution.

“Today’s sentences send a strong warning to those who seek to evade our nation’s tax laws – there is nowhere for you to hide,” said United States Attorney Ken Sorenson. “The United States Attorney’s Office and our law enforcement partners will relentlessly pursue and convict those who seek to steal from our country, and its honest tax paying citizens, through the operation of schemes to frustrate the lawful assessment and collection of taxes.”

“For years, Ms. Lastimado-Dradi directed her co-conspirators to conceal this theft from the public through trusts and business entities,” said Carrie Nordyke, Special Agent in Charge of IRS Criminal Investigation’s Seattle Field Office. “In the end, our agents followed the money, and this ruling has given that money back to taxpayers.”

IRS Criminal Investigation, the Treasury Inspector General for Tax Administration, and FBI investigated the case.

Assistant U.S. Attorney Gregg Paris Yates and Trial Attorney Sarah A. Kiewlicz of the Criminal Division Tax Section are prosecuting the case.
