Sounds like a guy either trying to run away, or a guy whose parents like to keep him away.
Let me run your stats and see if there's any missing persons reports for the last few weeks to months. I also need to know how much you had on you when you got here, how long you've stayed at that hotel, both as yourself and as the person you've replaced. What's the entire length of time you've been there? What's the name of the hotel.
I'm also going to have to go through your cell phone for missed calls, received calls, dialed calls, text messages, internet usage, and graphics. Were there any drugs on you or in your room? Are there any weapons on your or in your room? Do you have any keys or receipts or papers I can look through?
