As I posted before, this does appear to be an inside job, and the more facts are questioned, the more it does seem to be the answer.
I spent almost 35 fighting company fraud, working closely with police and in later years also involving our Security Department, staffed by ex-senior police officers.
In 99 cases out of 100 our company "wastage" was caused by insiders; staff who would steal, in those days, from £150 per week to one of our worst single cases, £30,000 in total (1970s). The latter involved a manager who was also an important London underworld figure who the Fraud Squad, Scotland Yard were after. Another involved £25K+ in the 1990s. Eventually we would catch them, and gain a conviction. But all were staff, and apart from burglaries or robberies that we sustained, the vast majority of our losses were "produced" by these people.
So yes, if you run a business of any type never trust anyone, and watch the staff who appear to be most "trustworthy" and hard working! Insiders will, if given the opportunity as I believe has happened in pscocoa's case, rob you blind!
