Two Oahu residents are pleading guilty to operating an illegal gambling business in Waianae.

Lloyd Robert Marshall and Nitta Mitsuko Marshall are also pleading guilty to 13 counts of evading currency regulations while handling proceeds from the business.

Federal prosecutors said Wednesday the Marshalls agreed to use their property as a site for illegal cockfighting contests and dice and card games between 2009 and 2011.  Police observed from 100 to 600 people at these events.  People attending paid parking and entrance fees.

The U.S. Attorney's office says the Marshalls each face up to five years in prison for the gambling charges and 10 years in prison for each of the counts related to evading currency regulations.

They are scheduled to be sentenced on Jan. 28.
