This really is discouraging news. Seems like all the hard work the volunteers have put in only to have someone steal the results of their work.
i can see how this happens. Especially in a non-profit organization. This particular organization provides a great and entertaining train experience for lots of people. it takes lots of vision to do something like this. It tends to create a lot of trust among the folks involved. The assumption is that everyone shares the same passion for the purpose. Unfortunately it is that trust that makes this kind of theft possible.
It has been my unfortunate experience that when some people are given unrestricted access to money then bad things happen. I have a friend who owns a business. Approximately 25 years ago, a woman showed up at the business in desperate need of a job. He made a place for her and she eventually became responsible for receiving money and paying the bills. She also became a part of their family. She never took more that a couple of days off. Well she got sick and was out for 3 weeks so my friend's daughter jumped in do the money part. She very quickly realized that there was a fairly sizable discrepancy with the money to the tune of about 300k going back 10 years. The temptation just got to great for this woman. Needless to say she got arrested, etc.
As others have said, this org needs greater controls, yearly audits and such.
I just hope they can recover from this theft and that it does not dampen the volunteer's spirit. Such a shame, good people doing good things and they get robbed.
