I would ask that the pin be analyzed, and the wipe. What would a pin be doing in the same area of the manufacturing of baby wipes? It's a terrible thought, but there may have been something ON the pin to add to the intent of the culprit.
Write down date, time, situation ...everything you can remember thinking and when you called who you talked to etc. You probably won't need any of that information, but if you do, you'll have it.
