During the second day of testimony from Francis Canellas, the finance director of now-defunct Dewey & LeBoeuf, the jury saw evidence that the firm’s top executives might have seen an email referencing accounting changes that state prosecutors contend were false.

Canellas, a key cooperating witness in the state’s case, answered questions about a Nov. 10, 2009 email from the firm’s then-chief financial officer, Joel Sanders, that was sent to chairman Steven Davis, executive director Stephen DiCarmine and chief operating officer Dennis D’Alessandro.
