Former U.S. ambassador sentenced to 15 years in prison

MIAMI — A former career U.S. diplomat was sentenced Friday to 15 years in federal prison after admitting he worked for decades as a secret agent for communist Cuba, a plea agreement that leaves many unanswered questions about a betrayal that stunned the U.S. foreign service.

Manuel Rocha, 73, will also pay a $500,000 fine and cooperate with authorities after pleading guilty to conspiring to act as an agent of a foreign government. In exchange, prosecutors dismissed more than a dozen other counts, including wire fraud and making false statements.

“Your actions were a direct attack to our democracy and the safety of our citizens,” U.S. District

Court Judge Beth Bloom told Rocha.

Rocha, dressed in a beige jail uniform, asked his friends and family for forgiveness. “I take full responsibility and accept the penalty," he said.

The sentencing capped an exceptionally swift criminal case and averted a trial that would have shed new light on what, exactly, Rocha did to help Cuba even as he worked for two decades for the U.S. State Department.

Prosecutors said those details remain classified and would not even tell Bloom when the government determined Rocha was spying for Cuba.

Federal authorities have been conducting a confidential damage assessment that could take years to complete. The State Department said Friday it would continue working with the intelligence community “to fully assess the foreign policy and national security implications of these charges.”

Rocha's sentence came less than six months after his shocking arrest at his Miami home on allegations he engaged in “clandestine activity” on Cuba’s behalf since at least 1981, the year he joined the U.S. foreign service.

The case underscored the sophistication of Cuba’s intelligence services, which have managed other damaging penetrations into high levels of U.S. government. Rocha's double-crossing went undetected for years, prosecutors said, as the Ivy League-educated diplomat secretly met with Cuban operatives and provided false information to U.S. officials about his contacts.
