Australian Erin Patterson found guilty of murdering three of her estranged husband's relatives by deliberately serving them poisonous mushrooms for lunch.

While Patterson has been found guilty of cooking the deadly mushroom lunch that killed three of her relatives and left another seriously ill, the motive is still unclear. There may simply be none. "You might be wondering, 'What is the motive?'" said prosecutor Nanette Rogers SC when she spoke to the jury in the trial back in April.

The world has met Erin Patterson as the murderous cook behind a mushroom meal that killed three relatives. But years before her courtroom infamy, the woman from Melbourne's suburbs divided opinions.
