In one case I was involved in, we did a complete surveillance of the premises after the CEO of a major company said he suspected there was a misappropriation of funds occurring. The surveillance cameras showed employees concealing tools, materials and other items. We could have stopped there, but in my experience, if there is one type of irregularity, there are usually others. I looked at the records thoroughly and found a number of other issues, including employees who were illegals as well as missing funds. As a result, we were able to uncover a plethora of issues occurring at the business and enable to company to prosecute those responsible for the missing items and funds.
