Zuckerman Spaeder is representing Zachary Warren, the 29-year-old former client relations manager of Dewey & LeBoeuf who was criminally charged alongside three firm leaders.

Partner Paul Shechtman in New York and Martin Himeles and William Murphy in Baltimore now represent Warren, Zuckerman spokeswoman Sarah Fait said.

Solo practitioner Michael Armstrong, who represented Warren at his arraignment along with McLaughlin & Stern partner Steven Hyman, said Friday that he and Hyman no longer represent Warren.

Warren is charged in two indictments with first-degree counts of scheme to defraud and falsifying business records, and fifth-degree conspiracy. Codefendants in one of the indictments include former firm leaders Steven Davis, Stephen DiCarmine and Joel Sanders. Prosecutors in the Manhattan District Attorney’s office claim the defendants defrauded and stole from the firm’s lenders, investors and others, and Warren “helped launch the scheme and helped cover up the fraud.”

The four men have pleaded not guilty. Murphy declined to comment about his new client on Friday.
