"“He was a notorious anti-Semite, sadist, fanatic Nazi,” Mr. Zuroff said in a telephone interview on Monday, after the British newspaper The Sunday Express reported his confirmation of Mr. Brunner’s death. “The only known interview we have with him was to a German newsmagazine in 1985, in which he was asked if he had any regrets, and he said, ‘My only regret is I didn’t murder more Jews.’ ”...Mr. Zuroff said a German intelligence official with extensive experience in the Middle East — “a reliable source in our eyes” — had informed the Wiesenthal Center about four years ago...The Wiesenthal Center did not announce Mr. Brunner’s death when the German operative reported it in 2010, or this year, when it published its annual list of fugitives without him on it."
