My actions probably ruined a person’s life.

This happened a few years ago but it still haunts me a bit.

For context I work at a very small business.

there was a customer that I would ring up somewhat frequently. Most of her haul would consist of items with “reduced” stickers. Like things that were super marked down because they were about to expire or were slightly damaged.
A lot of times when I rung her up, the stickers would be out of place, or on something that should not have been reduced. At first I ignored it thinking a newer employee was messing up a bit, and I just rang in the reduced price.

But I began to notice there would be “reduced” stickers on products I knew we had just gotten in, so there is no way they’d be marked down since they were fresh off the truck. I also saw a bunch of “reduced” and random price stickers stuck to the back of her phone. What really tipped me off was a 79 cent sticker on a container of collagen protein powder which was normally almost $50 or so. It still had a month before it expired. So It would never be marked down that low.

I mentioned it to my manager after she had left and a week later they caught her taking stickers off of actually reduced items, and sticking them to brand new items on camera. The cops were called. Apparently she was in the country on an expired visa and so I most likely ruined everything for her.
I feel awful, I just thought she’d get banned from the store. I didn’t think she’d get deported and her whole life uprooted.
Normally the police do nothing when we call about shop lifters.
I got a small reward from the store owners but at what cost? I always saw her as a bored rich housewife wife based on her fancy car and clothes but that doesn’t matter. I feel sick when I think about this.
