Despite having provided Mengele with legal documents using his real name in 1956 (which had enabled him to formalize his permanent residency in Argentina), West Germany was now offering a reward for his capture. Continuing newspaper coverage of his wartime activities, with accompanying photographs, led Mengele to relocate again in 1960. Former pilot Hans-Ulrich Rudel put him in touch with the Nazi supporter Wolfgang Gerhard, who helped Mengele cross the border into Brazil. He stayed with Gerhard on his farm near São Paulo until a more permanent accommodation could be found, which came about with Hungarian expatriates Géza and Gitta Stammer. The couple bought a farm in Nova Europa with the help of an investment from Mengele, who was given the job of managing for them. The three bought a coffee and cattle farm in Serra Negra in 1962, with Mengele owning a half interest. Gerhard had initially told the Stammers that the fugitive's name was "Peter Hochbichler", but they discovered his true identity in 1963. Gerhard persuaded the couple not to report Mengele's location to the authorities by convincing them that they themselves could be implicated for harboring a fugitive. In February 1961, West Germany widened its extradition request to include Brazil, having been tipped off to the possibility that Mengele had relocated there.
