The executive director of a Boston-area food pantry and his wife have been charged with shoplifting from a supermarket.

Ronald DiGuilio, executive director of the Randolph Community Food Pantry, and his wife, Rita, pleaded not guilty to the charge Tuesday at their arraignment in Quincy District Court. The case was continued until June 18.

The DiGuilios were arrested Monday night for allegedly stealing food and other merchandise from a Shaw's Supermarket in Randolph.

The 60-year-old Ronald DiGuilio tells the Patriot-Ledger of Quincy there's "more behind" the allegations. His wife tells The Boston Globe that the incident was a misunderstanding caused by trouble with the store's self-checkout machine.

The misdemeanor charge carries a maximum fine of $250.
