I watched "Dreams of a Life" on netflix.com about this case. A beautiful woman in her 30s just simply dies, despite being a vibrant and attractive person. Her death isn't noticed for 3 years.
The trailer to the film:
So many weird twist and turns of the story. So many loved ones and such a loner at the same time.
