Another former U.S. Postal Service employee is facing charges that he stole department store gift cards from the mail while on the job.

A federal grand jury returned an indictment Wednesday charging Vicente Martinez with two counts of mail theft.

Vicente was a postal clerk at the Volcano Post Office outside Hilo. He retired from the Postal Service last February after 18 years of service.

The indictment charges Vicente with stealing a letter containing three Macy’s gift cards in December 2011 and sealing a letter containing a Target Stores gift card in September 2012.

Retired letter carrier Albert Mamac Jr. pleaded guilty last October to two counts of stealing mail while on the job.

A federal judge sentenced him Tuesday to five years of probation. U.S. District Judge Derrick K. Watson also ordered Mamac, 62, to perform 400 hours of community service and pay $192 restitution.

Mamac admitted stealing a letter containing a $250 Foodland Super Market gift card in June 2010 and stealing a $100 Target Stores gift card in October 2012.

Someone using Mamac’s wife’s frequent shopper card redeemed the Foodland gift card at Sack ‘N Save food store while Mamac’s daughter redeemed the Target gift card in Reno, Nev.
