HAVANA — The trial of a U.S. government contractor facing up to 20 years in jail on charges he sought to undermine Cuba’s government wrapped up Saturday after both sides gave closing arguments, but with no indication of when a verdict might come.

A statement by the Cuban government Saturday night said that during the trial Gross accepted some responsibility but added that he had been “used” and blamed the company that sent him to the island.

The fate of Alan Gross, a 61-year-old Maryland native detained for more than a year since being caught bringing communications equipment onto the communist-run island, was in the hands of a five-judge panel.

Gloria Berbena, a spokeswoman for the U.S. diplomatic mission on the island, reiterated after the government statement was released that no verdict had been announced. She said Gross’ Cuban lawyer would be notified when a verdict was reached.
