SAN DIEGO — A Navy lieutenant involved in an overbilling scheme that cost the service tens of millions of dollars is going to prison.

Gentry Debord was sentenced Thursday in San Diego to 30 months in federal prison. He pleaded guilty last year to a bribery conspiracy charge.

Debord, a onetime Navy supply officer of the year, acknowledged that from 2007 to 2013 he supplied confidential information to a Malaysian defense contractor in return for cash, prostitutes and luxury hotels stays.

Contractor Leonard Francis had a Singapore-based company that supplied services to Navy ships in the Pacific. Authorities say he overbilled the service by $35 million.

Debord is among 16 people charged in connection with the corruption. Ten current or ex-Navy officials and three company officials have pleaded guilty, including Francis.
