The former Chief of the Criminal Division of the U.S. Attorney’s Office for the Eastern District of Pennsylvania, Louis Pichini, was chosen to perform an audit on the Philadelphia Sheriff’s office by the city controller’s office, The Philadelphia Inquirer reported Tuesday.

Pichini serves as director of Deloitte Financial Advisory Services and was chosen over about 15 other names.

City Controller Alan Butkovitz said the contract was for $462,000, and Pichini’s team is to complete the work by June. He called for outside help after his auditors couldn’t document accounts with assets of $53 million.
