SAN FRANCISCO — Former Korn/Ferry executive David Nosal should be imprisoned for 27 months for stealing trade secrets from company computers, the U.S. attorney’s office said today in a high-profile white-collar crime case.

“A sentence of imprisonment in this case will send a strong message to those in the business world who are contemplating stealing information from the computer systems of former employers or competitors that such conduct is criminal and will put you in prison,” Assistant U.S. attorneys Kyle Waldinger and Matthew Parrella wrote in their sentencing memorandum in United States v. Nosal.
