In 2018, Lieutenant Eric Yiu, a veteran detective who investigated financial crimes, was indicted on six felony counts of making false statements on his state tax returns. He pleaded guilty in March 2019, as part of a plea agreement, to filing fraudulent tax returns for three years, and May 2019, he was ordered to pay $11,654 for tax evasion, but avoided jail. In late November 2020, Louis Kealoha was sentenced to seven years in prison, while his wife Katherine Kealoha was sentenced to 13 years in prison. Due to precautions related to the concurrent COVID-19 pandemic, Louis Kealoha was allowed to start his sentence in April 2021.
