Merrill Lynch has released Barbara Scholl from her position as managing director and head of distressed fixed-income research, according to officials at the firm. She did not respond to messages left at her office and her residence. The officials say Scholl's work was mainly on behalf of a proprietary trading effort at Merrill. One of the officials, and another member of the distressed community, expressed surprise that Scholl was let go, as her group was believed to be profitable. Graham Goldsmith, head of the firm's distressed business, referred calls to a firm spokesperson, who did not respond by press time last Thursday.
