The Manhattan District Attorney’s Office has announced two high-profile appointments. Polly Greenberg has been tapped as chief of the major economic crimes bureau and David Szuchman has been appointed a deputy chief of the investigation division. The appointments fill positions held by Richard Weber, who recently accepted an appointment as chief of criminal investigation for the IRS.

Greenberg, a New York University School of Law graduate, first joined the office in 1993, working in the appeals and special prosecutions bureaus. After going into private practice in 2000, she returned to the office in 2005. Greenberg was appointed deputy chief for the major economic crimes bureau soon after its establishment two years ago. Her latest appointment is effective April 16.

In addition to his new role, Szuchman will continue as chief of the cybercrime and identity theft bureau, a position he has held since rejoining the office in 2010. Szuchman first joined the office in 1997 after graduating from Hofstra University School of Law. He left in 2001. Immediately before rejoining the office, Szuchman was the director of the 600-employee New Jersey Division of Consumer Affairs. Szuchman, who started his new duties on April 3, joins Daniel Brownell as a deputy chief of the investigation division.
