A Soviet KGB agent last year wanted Sgt. Clayton J. Lonetree to point out possible homosexuals, "liberal types, dopers or drunks" among U.S. Marine guards at the U.S. Embassy in Vienna, Lonetree's espionage court-martial was told yesterday.

Naval Investigative Service (NIS) special agent Thomas E. Brannon said Lonetree also told NIS interrogators that Soviet agent Alexei (Uncle Sasha) Yefimov sought names of any Marine guards who dated Austrian women, and asked Lonetree to bug the ambassador's office with an electronic listening device.

Brannon said Lonetree declared he refused to plant the bug, and discussed one Marine with Uncle Sasha, whom Lonetree met in the course of his love affair with Violetta Sanni, a Russian translator, while he was a guard at the U.S. Embassy in Moscow from 1984-6.

The 25-year-old American Indian from St. Paul, Minn., is being tried before eight officers at Quantico Marine Base on 13 counts of espionage and related charges, and faces a possible maximum life sentence if convicted.

The court was told that a search of Lonetree's Vienna quarters, where he was assigned after Moscow, produced a set of "contact instructions" from Uncle Sasha, a list of six U.S. intelligence operatives in Vienna, and love letters to and photographs of Sanni.

Books seized included "The Complete Spy" and "Essentials of Leninism," NIS special agent Gary L. Hardgrove said.

He said searchers also found a black jewelry box that Lonetree described as a "gift from Sasha" and a pair of women's shoes, a gift for Sanni.

Lonetree's defense attorneys tried unsuccessfully to prevent "Essentials of Leninism" from being admitted as evidence, on grounds it was "extremely inflammatory" in the minds of the officers and not relevant to Lonetree's state of mind at the time he had contacted the KGB.

Hardgrove testified he believed Lonetree's motivation in his contacts with the KGB was "hatred against the white man." He said Lonetree had told his interrogators, "There are still good Americans out there, but I thought of the ugliest American I could think of when I handed over those photographs {of U.S. intelligence agents in Vienna}."

The hearing has been told in an earlier session that Lonetree believed Sasha already knew the identities of these agents.

The defense contends that Lonetree did not intend to pass anything of value to his KGB contact, and that items he did hand over that were classified were already known to Sasha.

The list of six U.S. intelligence operatives in Vienna was never given to Sasha. Items Lonetree passed to the Soviet included floor plans of the U.S. Embassy in Vienna. Under cross-examination by defense lawyer Michael Stuhff, Brannon conceded that Lonetree had told him the documents were not locked away. The defense sought to show the low value of the plans by stressing that they bore the names of the Austrian "char force," as Stuhff called the women assigned as floor cleaners.

Lonetree also passed on a "quick index list," a one-page internal telephone list for the embassy.

Stuhff told reporters during a recess that the NIS agents had made a "very sloppy distinction" between Sasha's requests for important information and the low-value answers Lonetree had provided.

The NIS agents had persuaded Lonetree that the information he passed on was valuable, Stuhff said.

According to excerpts from a transcript of taped interrogation sessions by the NIS, Lonetree told the special agent, "Well, at least I didn't give them anything really priceless." And said he was "afraid Sasha may have figured out I was giving him an outdated list or something. It was somewhat roughed up copies."

According to the transcript, Lonetree agreed with the NIS agents' paraphrasing of his intent as "trying to whet Sasha's appetite," and had said, "I was just trying to satisfy {Sasha} to make it last longer without him being suspicious."

Stuhff has said Lonetree's intention in passing the information is "crucial" to the case, asserting that he did so as a self-appointed double agent, trying to entrap the Soviet agent.
