SAN DIEGO, AUG. 15 -- A retired Navy radioman was convicted at a court-martial Friday of passing confidential U.S. intelligence documents to a branch of the Philippine military and was sentenced to eight years in prison.

Michael Allen, of Ponchatoula, La., had faced possible life imprisonment, but a six-officer court-martial imposed the eight-year sentence Friday after returning the guilty verdict. Allen also was fined $10,000 and ordered to forfeit the remainder of his retirement pay, the Navy said.

The jury found Allen not guilty of two of 13 espionage and espionage-related charges and dismissed a third. The jury began deliberations Thursday after a seven-day court-martial in a San Diego Naval Station courtroom.

During the court-martial, Lt. Mark Waggoner, the assistant military prosecutor, portrayed Allen as "nothing less than a thieving traitor."

Allen, a former senior chief radioman who served in Korea and Vietnam, settled in the Philippines when he retired from the Navy in 1972 after 22 years of service.

Navy officials said Allen was tried in a military court because, as a reservist, he could be recalled to active duty.

Allen was working as a civil service photocopy clerk at the Cubi Point Naval Air Station in the Philippines when he was arrested Dec. 4 after a five-month Naval Investigative Service probe.

His job had consisted of photocopying documents and delivering them to appropriate Navy offices at the air station.
