She lives in the US. I do know the state but that is all. She moved there just a few days before I stopped hearing from her. The detail that ended up consuming me with worry, in the beginning, was when she, in her last e-mail, asked me if I wanted her to stop with ballet, and continue with it at home, as I previously had expressed concern with how much of her can be seen while she's training and performing. Back at that time, she explained how her ballet dress properly covers her, and I told her that I was relieved to hear that. So despite this, she in her last e-mail suddenly ends up asking me if I want her to quit ballet, despite that she loves it, and knows that I love that she does it. This after arriving at a new location. When I replied, I of course told her that I don't want her to quit, but as I kept not hearing from her, my mind of course started running wild with thoughts of some group of scary guys having watched her training, and she wanted me to tell her to stop with it so nothing would happen to her. When I first replied, I did of course ask if there was a reason to why she asked me that... regrettably, I intentionally waited a day with replying, and now that has left me thinking that I didn't find out the details behind what she asked me in time, so they ended up raping her, just because I waited with replying. And now she can't speak with me, again, because of it, or she took her life, afterwards. In such a case, I wish she would've told me, then, first, so I could've joined her in death and met her in another life, instead.
Aside from knowing that she has an elder brother and yet elder sister, and that her father is rich and has a pretty unique job, and knowing her story about memories from growing up, and knowing what other states she's lived in before... other than those things, I know nothing that could help me find her... and I just can't see how what I do know could help me track her down. I know a bit about how she looks, but I don't have a photo of her. She was going to show her photo to me around when she disappeared.
I do love her. I never got to telling her that.

I felt that I wanted to wait with saying it. Heh, I pretty much started falling in love with her just two days after I had met her.... -_- she was just so damned perfect.... and the more I talked with her, the more perfect I learned that she was.
