This is a weird question I know that, but I have talked to a couple of people and we're all conflicted. To render a much longer story short, about 10 years ago when I was getting back into the work force after having kids I was briefly an admin assistant at a college. Part of my job was reconciling expenses for my superiors. Most of it was mundane, except my direct boss kept failing to give me receipts or gave me receipts that were really just scribbles on a piece of paper for art. When I asked questions he would always insist that Kenya or Thailand or wherever he had been didn't have receipts.

It was a line he said often, and it seemed likely my predecessor had just accepted it. But I traveled extensively and knew that couldn't possibly be true. I was knew and had no proof of wrongdoing so I would send those expenses (always substantial and often cash withdrawals )on to the next level with a note that no receipt existed as per internal protocol. Over time I also noticed that the art or whatever he purchased was not on display in our offices, but it was a big campus so I assumed it was possible it was in one of the other buildings. Still I asked a lot of questions as the months went by and each trip's expenses looked the same odd way. 

He fired me during my probationary period in a way that led to the institution retracting his termination letter and giving me substantial severance in addition to my unemployment. (He put in writing that I was failing to read his mind so you know, not a thing that wanted me to take to an employment lawyer) It was frustrating and seemed catastrophic at the time because my husband had just been laid off but ultimately I got a better job with great benefits elsewhere. 

After I left, my replacement also noticed the bizarreness of his expenses. She went a step further and actually set up a meeting with a superior and took the risk of directly pointing out the pattern of money leaving for goods that didn't seem to exist within the institution. They called me in to ask me some questions and I was able to validate that he was indeed claiming receipts didn't exist in various countries. Eventually because of our combined paper trail a forensic accountant got involved. The rumored amount embezzled was 85K, there was no question he had been embezzling but he made a deal to repay it and left the institution eventually. He went on to work elsewhere in another state which I only know because I used to see him at conferences for our shared field. He stayed in academia though at a much less prestigious university. I'm on the industry side, and frankly we pay better so I was always privately amused when I would run into him. Until now I never said a thing to anyone on the industry side. 

I do not know what happened at his last institution, but he has been applying on the industry side, and I'm on the review panel at my job. On paper his credentials are great, but we have corporate cards and we travel. Part of me says he's probably learned his lesson, and part of me remembers just how arrogant and blatantly he was stealing when we worked together. WIBTA if I gave HR a heads up?
