A 1992 letter to the editor of The National Law Journal identified in court documents filed late last month in the kickback case against Milberg Weiss & Bershad provides direct evidence that federal prosecutors have William Lerach in their sights.

The letter, along with a preceding article in the NLJ, are mentioned in papers that were filed as part of a Jan. 31 plea agreement with Steven G. Cooperman, a former named plaintiff for Milberg Weiss. Cooperman has admitted he received secret payments from the New York securities firm in order to serve as lead plaintiff in several shareholder class actions.
