The interview, if one could call it that, was painful to watch. The interviewer did not have any questions, and seemed to be waiting for some sort of audience to bring questions to Shannon - but there was no audience. On the upside, it shows us who Shannon is. She seems to have a healthy reaction to the disorganized interviewer ... doesn't appear to be on medication, has a quick wit, and certainly doesn't appear to be someone contemplating ending her life.
Between March 2014, and now, she was married, but that marriage is now on the rocks. During the interview, they discuss more voice work at the end of the year, which is now, so there's no shortage of work. For me, that helps rule out any possibility of suicide. Much can change in 8 months, but Shannon seems upbeat even though the interview was obviously not a career boost ... I suppose what I'm trying to say is that she takes it in stride.
If suicide is off the table, that leaves: husband did something to her, she left the house after midnight and experienced an accident, or she was grabbed off the street in the neighbourhood ... none of which bodes well.
