Prosecutors in the Dewey & LeBoeuf criminal trial continued hammering away at the firm’s former leaders on Wednesday, walking jurors through a series of emails to support their allegations that the executives used phony accounting to dupe lenders and investors.

The day featured continued testimony by former Dewey finance director Francis Canellas, a key cooperating witness in the Manhattan district attorney’s case. The emails, together with Canellas’ testimony, appeared to show that former Dewey chairman Steven Davis and former executive director Stephen DiCarmine knew of at least some of the “accounting tricks” described to the jury over the past month and a half of trial.
