Help!

My friend is visiting New York (I live in California and am not with her) and she texted me at 1 am saying she was almost raped and murdered. Her texts sounded like she was drunk (lots of spelling errors and kind of not making sense) but now I'm super worried. I've tried calling her, texting her and messaging her on Facebook. She isn't responding. I didn't see her texts until I woke up so I hope she's okay now. I don't know what to do!!
