Let me preface this by saying that anyone who can speak more than one language is awesome. That's why I usually don't post when I see an error in grammar, punctuation, or spelling. No one is perfect, and writing in a language other than your first is pretty cool!
Sheriff John's new quest says:
Hi, sit down please. I need to talk with you, something happened it our city. Yesterday one of our citizens have reported that her jewelry have disappeared. Yes, just disappeared. It was unique and expensive collection. Full of diamonds and other precious stones, and gold. Also a few days ago I saw a suspicious character walking about the city. That may be a thief. I think you can find him near New Settlement. Take your gun and check my suspicions.
It should read:
