A trucking company supervisor pleaded guilty Tuesday to stealing more than $300,000 from the U.S. Postal Service by improperly using government-issued fuel cards, U.S. Attorney Paul J. Fishman said.

Rufus Ward, who worked at two trucking companies in Ocean Township, N.J., that contracted with the Postal Service to haul mail, admitted purchasing fuel and cigarettes for personal use between 2005 and 2009. Ward, 67, faces up to 10 years in prison and a maximum fine of $250,000. Ward agreed to pay restitution of about $365,000. He is scheduled to be sentenced Sept. 13. - Darran Simon
