Kidnapped

It seems like some one is being kidnapped. Probably a girl. We are looking for some clue in a rough neighborhood. We drop by 3 places, one of them is an arcade store. The other one is a miniature store, which only trade miniature model and not selling the unfinished model. I saw a miniature of Flinstone’s car made from real skin. Apparently I was looking for a small screwdriver. The other store also sell some sort of miniature which I intended to buy.
The clue is given to me by a girl written inside an envelope that I left behind. The second & third clue seems to be written by the same guy on the same envelope.
