A Swiss woman is dead after trying to live on sunlight alone.

It was part of a spiritual journey for the woman, identified in the story with the fake name Anna Good, who was reportedly inspired by a 2010 documentary In the Beginning There Was Light. The film tells the story of people who follow a concept called breatharianism and they claim to survive without eating or drinking anything for weeks, years or even decades.

Good saw the movie in 2010, the Swiss newspaper Tages Anzeiger reports. She started on the diet, going so far as to spit out her saliva.

In early 2011, after her children hadn't heard from Good, they went to her home and found her body.

Police conducted an investigation and on Wednesday, district attorney Thomas Burgi told the newspaper the case was closed because there was no evidence of "foreign influence" in Good's death.
