I feel like this must be common in most cases, but I have only one data point to back it up:
In 2014, I was working for a startup when I found out the founder had embezzled/stolen our investor money, lied to creditors, stolen employee salaries and W2 tax contributions, etc. and used the money to fund his big apartment, private schools for his children, two full-time nannies, and a nice BMW. After we found out we all resigned and the following Monday were sitting in the DA's office (financial crimes). The DA decided to pick up the case (fortunately, mostly because it was an absolute slam dunk after he confessed to it all through email) and it took them literally 3 years of interviews, research, etc to take the case to grand jury. Eventually, he plead guilty and has to pay back roughly 650K to employees + investors, but NYC must have spent well over 1MM to get that money back to us.
The only person that actually paid a lawyer in this case was the person who plead guilty, and of course, the tax payers of NYC
