Another Nazi war criminal, Walter Kutschmann, who was accused of killing 20 Polish university professors and their families, and who lived here under the name of Pedro Ricardo Olmo, appeared before a judge in Mar del Plata in the south of Buenos Aires Province. He denied the charges, maintained he was Pedro Olmo, and was released.

The files also tell how many of thesewar criminals emerged after a decade or so in the country, trying either to obtain passports in their real names or seeking approval from the Argentine and German Governments to travel abroad. Under His Own Name

Josef Franz Schwamberger, who entered Argentina in 1949 on an Italian passport using his own name, tried to obtain a German passport in 1954. He also applied to the Argentine Government for permission to travel to Chile.

Mengele, who entered Argentina with a Red Cross passport in 1949, succeeded in obtaining an authentic document approved by the German Government.

Even when war criminals were identified by Nazi hunters or the German Government requested their extradition, the Argentine authorities often took years to find them and take action on the requests.

In 1975, West Germany asked for the extradition of Kutschmann and he was identified within months with the help of Jewish groups in Argentina and abroad. Under the Olmo alias he was living in the beach resort of Minamar and working as the manager of a Germany electrical concern.

But he escaped justice in his 1983 appearance before a Mar del Plata judge and was not caught until November 1985. He fell ill within months and died the following August while negotiations over his extradition were still in progress.

The file that perhaps has drawn the most attention turned out to be little more then a collection of press clippings and false sightings.

Debate over the whereabouts of Hitler's deputy, Martin Bormann, has gripped the imaginations of Nazi hunters for years, with some saying he died in the fall of Berlin in 1945 and others saying he fled to Argentina with millions of dollars in gold and currency.

According to the files released today, the federal Argentine police had no record of Bormann entering the country. But still, two folders were maintained, filled with press clippings of Borman living in the jungles of Colombia, living as a priest in a commune in Bolivia and living in remote Argentine villages.

Despite the few revelations in the first set of documents made public by the federal police, Nazi experts say much more could be coming from other Governmental agencies, like the central bank, the Foreign Ministry, the intelligence service and the provincial police.
