She initially performed professionally as a classical musician, but was persuaded to move to night club playing by Mischa Rosenbaum.
He claimed that Nussenbaum struck him on the arm and shoulder with a stick before he hit her on the forehead, causing injuries from which she subsequently died.
Rosenbaum hid her unconscious body behind a soundproof curtain,[1] where she was found some hours later by Moya Engels, a dancer.
Judge Saul S. Streit accepted the plea on the recommendation of New York City District Attorney William C. Dodge.
In agreeing to the plea, Dodge believed it wise to uphold the reputation of Nussenbaum and to forgo the $800 daily expense New York would save by not having an extended trial.
