Ask A PI: Thomas Martin answers questions people have about private investigation

What is a PI’s most common type of case?

I think the most common PI case, at least for most private investigators or agencies, involves cheating spouses. While we do our share of those cases, they only represent about 5% of our business in our five California offices and casework throughout the United States. Our most common case at Martin Investigative Services involves clients throughout corporate America that retain us to determine who is stealing time, money or product from them.
