The criminal investigation into Dewey & LeBoeuf’s ex-chairman Steven Davis is moving ahead, as the last remaining member of the firm’s ‘office of the chairman’ management team departs the disintegrating firm, reports The Am Law Daily.

Partners still with Dewey as of last Thursday (10 May) received an email telling them to retain all documents in their possession related to a variety of the firm’s business practices, according to three partners who received the email.
