While there may be few people left in Dewey & LeBoeuf‘s 1301 Avenue of the Americas headquarters, a criminal investigation launched by the Manhattan District Attorney’s Office into the actions of the rapidly vanishing firm’s ex-chairman is moving ahead.  

Partners still with Dewey as of May 10 received an e-mail telling them to retain all documents in their possession related to a variety of Dewey’s business practices, according to three partners who received the e-mail. The so-called document preservation notice, sent by Dewey assistant general counsel Esther Bloustein, said the request was being relayed “in connection with” the D.A.’s probe of former chairman Steven Davis, who has denied any wrongdoing.
