There are more persons in a lab than only high qualified researchers. Cleaners for example. And one bat might not be much, but if your job is to dispose 20 or 50 of them and you can just go a few hundred meters and sell them to a vendor for a few bucks? I don't say that is what actually happened there, I just think that this would be one possibility.
