My group had got a bad containing items such as an Animal Book for kids, Gum, Ear Rings, A Mirror Lip Gloss and A Picture. One fact we can say is that the owner is a female. She probably has kids trying to learn foreign languages, this can be proven by the kid books in Chinese and Greek. Another fact we can say is that, she has been to Hong Kong. Looking at the Tooth Paste and Brush from a chinese hotel and a map of Hong Kong, it is also a posibility that the Chinese kid book links to this.
It starts of confusing but as more evidence of the owner starts showing, it becomes more and more obvious. It cannot always lead us to the exact person, but it can be close enough to make an estimate. But by looking at the pound sticker and the Hong Kong map, I had a feeling it would be Mrs. P. I was right.
