A lawyer for former Dewey & LeBoeuf chief financial officer Joel Sanders urged jurors on Thursday to discount the testimony of key cooperating witnesses in the Dewey criminal trial, saying the witnesses changed their accounts after meeting with New York prosecutors.

Manhattan Assistant District Attorney Peirce Moser, meanwhile, began to deliver the state’s final plea to convict Sanders, former Dewey chairman Steven Davis and former executive director Stephen DiCarmine, insisting that the defendants “lied” and “cooked the books” to inflate the firm’s bottom line.
