Those are the "known" losses.  And these could represent the tip of an iceberg.  Statistically about 90% of an iceberg is unseen, underwater.   And with such little repercussions against the one nailed for taking YC funds, this could plant ideas for schemes who knows where.  Lets not forget about Public Works payments with scanty back up that the materials or services were actually received.  I'd say this is a loophole big enough to drive the PW largest truck thru.  I'd also suggest that an internal auditor should be reviewing the "levelizing" of contractual bids.  AND should sign off before awarding of the "selected" bid.  Same for bonus calculations.

Plenty of potential stuff to be confirmed by an internal auditor, instead of merely a few mentioned by this casual observer.  Mendelsohn could probably provide a much more comprehensive list.

I think your $80K estimate is too high.  And it could become a part time position after 6 months, or a year, for example.   By comparison, what was the HR guy's salary level?
