In June 2019, a jury in federal court convicted Kealoha (along with his wife Katherine and two Honolulu police officers) of using their law enforcement positions in an attempt "to frame Katherine Kealoha's uncle for stealing the couple's mailbox in 2013" and subsequently lying to federal investigators. The Kealohas pleaded guilty in October 2019 to financial crimes arising from the mailbox theft (specifically bank fraud and identity theft); two others were convicted in connection to the same case. In November 2020, Louis Kealoha was sentenced to serve 8 years in federal prison. Due to precautions related to the concurrent COVID-19 pandemic, Louis Kealoha was allowed to start his sentence in April 2021. His wife, Katherine, received a sentence of 13 years.
