Reaching the home stretch and preparing to rest their case, Manhattan prosecutors in a trial against three former Dewey & LeBoeuf executives called to the stand Wednesday a forensic accounting consultant who testified that multiple accounting adjustments each year lifted net income by tens of millions of dollars.

Meanwhile, the defense presented the jury with its own calculations, attempting to undermine the consultant and sow confusion and doubt for jurors.

Assistant District Attorney Gregory Weiss called Jonathan Vanderveen, a managing director with consulting firm Alvarez & Marsal who focuses on forensic accounting. He is expected to be the second-to-last witness for prosecutors, who have accused Dewey chairman Steven Davis, executive director Stephen DiCarmine and chief financial officer Joel Sanders of overseeing a scheme to falsely inflate the net income of the now-defunct law firm through a series of accounting gimmicks.
