BOSTON - Former State Representative and Dartmouth Select Board member John George, Jr. pleaded not guilty to charges of obstruction of justice Tuesday in U.S. District Court in Boston.

The 70-year-old is already serving a 70-month sentence for embezzling hundreds of thousands of dollars from the Southeastern Regional Transit Authority. In April of 2015, he was sentenced to the 70 months in addition to restitution and forfeiture of $1.38 million. He told the U.S. District Court he only had about $28,000 in cash, but officials soon uncovered more than $2.5 million in cash stashed throughout different safe deposit boxes at banks in New Bedford and Fairhaven.

That discovery led an indictment last month on charges of obstruction of justice, which carry a sentence of 10 years in prison and fines up to $250,000.

A spokesperson for the U.S. District Court said George consented to voluntary detention without prejudice after pleading not guilty. An initial status conference is set for June 20th.
