A Cuban spy convicted of infiltrating a Cuban exile organization in Florida was released from U.S. federal prison early Friday after serving 13 years of his 15-year sentence, his lawyer said. Rene Gonzalez, a Chicago native who has dual U.S. and Cuban citizenship, is the first of the so-called \"Cuban Five\" group of jailed spies arrested in 1998. The five were convicted in 2001 of being part of a spy ring called the \"Wasp Network\" that sought to infiltrate and report back to Cuba on south Florida U.S. military installations.
