Plum and gray capsule no marks

[Theresa Moore]

I took a capsule in a blister pack, (easy to open, with a yellow pull tab) it was gray with plum or purple from a preschooler. It had no marks, letters or signs on the pill or the pack. Please help, mom stated it was it was not hers, so I really need help to identify, because next step is to turn over to police, and I really don't want to have a preschooler or his mom arrested for drug possession if it is just a simple misunderstanding or if it came from a staff members purse. We keep them locked up but it could have fallen out... please any help..
Thanks

Could you post a clear picture of it? The reason I ask, is that it seems to me that one of the over the counter acid reflux medicines comes in a packaging and color scheme like you are describing, but for the life of me, I can't remember which it is at the moment. Maybe with more information, we can narrow it down for you.

The police id it as stacker 3, but the police also said it usually has an id number. No charges will be filed. Naturally all the staff deny taking such pills, but several parents admit to using this and having it in their purses so we can only hope they will be more careful.
