An Australian newspaper has made public secret jury notes that reveal why Lindy Chamberlain was convicted of murdering her baby daughter Azaria Chamberlain 30 years ago.
They detail what the jury was thinking when it threw out Lindy Chamberlain's story that a dingo had taken her baby, and convicted her of killing her daughter at what was then Ayers Rock in August 1980.
The notes, handwritten by the the foreman in the 1982 trial, were part of Northern Territories police files given to the Courier Mail.
They show the three women jurors - a teacher and two housewives - voted for a conviction while at least four of the nine men had to be persuaded that she was guilty.
The jurors were puzzled by Lindy Chamberlain and her husband's unemotional behaviour and why they never joined in the search for their daughter's body.
Michael Chamberlain was convicted of being an accessory.
It was to be six years before Lindy Chamberlain was released and the couple exonerated.
Police documents and exhibits from the case are destined for Australia's National Archives because of their historical importance.
