A federal judge sentenced a former teller for the credit union for TheBus employees, retirees and their families to 13 months in prison Monday for embezzling more than $350,000.

Jenny Nishida, 41, has until Oct. 14 to turn herself in to begin serving her prison term.

In addition, U.S. District Chief Judge Susan Oki Mollway ordered Nishida to pay the OTS Employees Federal Credit Union’s insurer $330,459 restitution.

Oahu Transit Services is the company that operates the city bus system.

Nishida pleaded guilty in May to making 122 payment entries totaling $358,685 into her and her family members’ Visa credit card accounts from 2009 to 2011 for payments not actually made.

OTSEFCU Board Vice Chairman Luis Navarro said Nishida’s theft was the greatest loss the credit union had experienced in its history. He said the credit union’s losses include having to investigate what Nishida did, defending itself against Nishida’s attempt to avoid paying back the money by filing for bankruptcy and the loss of its members’ trust.
