So there's a few things I was able to gather so far.
#1 - She works in a mall
#2 - She lives in Nova Scotia
#3 - She has most definitely stolen from this specific mall considering both specifically named stores have the same address
The best part about all of this is that she was bragging about how she doesn't give a shit if people lose their jobs over her thieving. She was also talking about how she could "use age to her advantage to avoid being arrested." If I'm not able to ever get in contact with this bitch, I will at least call both of these stores and ask them if they sell this specific piece of clothing, then I will ask them to check their security cameras for the afternoon of June 25th, and if it's true that she's dumb enough to be stealing from the fucking mall she works in, then it's fairly safe to say that they will be able to identify her.
Technically, this is all I can do on my end for now because I still have no way to directly contact her and create a potential chimp out, but at the same time considering I'm about 90% sure that everything here is accurate, I may find it even better for her to seemingly out of nowhere get arrested for her theft.
