I didn't say they have no connection to her or what may have happened to her. I don't know what happened to her and I don't think you know, either. She may have been raped/murdered/torutured/sold into slavery/run off on her own/kidnapped/whatever. You didn't say you fear she was raped and murdered, you said she was raped and murdered. If you know that to be the case, I suggest you contact authorities because you obviously have more information than they do.
Neither did I write that I know she was raped and murdered.
I wrote what I think is likely to have happened. I pray she will be found safely. I doubt this will be so.
I try to avoid redundant and trite language so I tend not to use phrases like IMHO, I think, etc. unless the reader might be confused. Obviously that happened in this case.
