Ex-CIA Director Stansfield Turner said he finds the William Kampiles case "terrifying" because Kampiles, a 23-year-old former CIA watch officer, betrayed the United States not for money, but "for kicks."

Recruited to the CIA from Indiana University in 1977, Kampiles, the son of immigrant parents and a one-time altar boy, wanted to be a covert agent.

But he found his CIA job routing message traffic to be boring. When he didn't get a transfer after a year, he quit.

And when he left, in anger he took a top-secret manual giving detailed workings of the extremely sensitive KH-11 "Spy in the Sky" satellite.

He later said that he sold the manual to an agent named "Michael" at the Soviet embassy in Athens for $3,000.

The CIA became concerned when Kampiles wrote to a former CIA colleague that he had been in contact with the Soviets and that they were seeking information. Kampiles offered to give them "disinformation" as a CIA double agent. Later he told former colleagues that the Soviets already had given him money, and CIA suspicions increased -- the KGB doesn't give money for nothing.

Convicted of espionage in 1978, Kampiles was sentenced to 40 years in prison.

His information ruined a major U.S. intelligence coup, officials said. The Defense Intelligence Agency said a main reason he betrayed his country was that he was "egocentric."
