The media are to blame.
The poor woman went missing by the river on the 27th of January. However, because she was pretty, and a woman, the media jumped on her disappearance with day upon day of speculation - did she fall in, was she pushed, has she been abducted etc.? It has been the headline story ever since with little nibbles of "what ifs" but no real news.
It now turns out that the police had attended a disturbance at her house a week or so earlier because, sadly, she was suffering menopausal depression and had alcohol issues. According to the head of the independent search and rescue effort had those things been known from the off the search would have gone very differently. And so the media speculation begins again...
I cannot imagine the hell her family and friends have and are going through because of all this media coverage. People go missing all the time so why this one instance was made a star story is a mystery.
