For Daniel Vaccaro, internal investigations are all about creating your own playbook, a far cry from the structure of civil litigation and its linear cadence. The key to success in these cases is creativity.

core/paragraph

“You’re often trying to do [an internal investigation] in a confidential setting with very few people necessarily knowing that an investigation is ongoing. So, your ability to think how you’re going to acquire information and evidence and certain aspects of what you need to do without necessarily everybody knowing what’s going on. You don’t have a scheduling order that sets out the things you’re going to do. You don’t have a rule book that sets out the things you’re going to do,” said Vaccaro, litigation practice group chair and partner at Michael Best &amp; Friedrich.

“Thinking about the order in which you’re going to talk to people, how you’re going to approach them — there’s a lot of that aspect of the process that’s very different from the mind of civil litigator who’s solely focused on the rules and the process,” he continued.

Practicing from the firm’s Milwaukee office, Vaccaro’s 35-year career includes time as a federal and state prosecutor and defense lawyer with more than 135 jury and bench trials. He represents corporate clients in government investigations, enforcement actions and complex civil litigation. He is often called upon to structure and conduct internal investigations.
