Zachary Warren, a young lawyer and former junior manager at Dewey & LeBoeuf who faced criminal charges alongside three firm executives, has formally put the case behind him and has relaunched his legal career at one of the country’s top law firms.

Ahead of schedule, a Manhattan judge dismissed fraud and conspiracy charges against Warren on Friday under a deferred prosecution agreement reached last year, according to his attorney, William Murphy. He had been accused by New York prosecutors of helping conceal Dewey’s precarious finances before the firm collapsed in 2012.
