There could be yet another scandal at my workplace

Someone in another department might be stealing packages now. I work in procurement and our shipping/receiving guys have noted that two different boxes they had delivered to a department have gone missing. Both were delivered on separate dates, but around the same time, and none of us think it's any coincidence that both packages from that department just up and disappeared around that time. They recently hired a new secretary who had previously worked here, who my boss says he heard she had been let-go before for doing something similar. If that's true, then she's looking pretty damn suspicious right now. Not sure what she would want with the packages, though. One was training books, the other was signs. I'm hoping somebody who as access there just cluelessly tucked them away somewhere and forgot about them or something and they'll both turn up soon. But if not and they were indeed stolen, that's two scandals we've had here recently! First fraud with someone making illegal purchases with a company credit card, now we might be looking at theft. We'll just see what comes up, but it does not make our organization look good in the least bit and it makes my department in particular look terrible!
