Australia's Erin Patterson is facing life in prison after being found guilty this afternoon of triple-murder. 

The 50-year-old appeared emotionless as a jury delivered its verdict to the Supreme Court, ending seven days' deliberations.

It agreed Patterson deliberately fed members of her estranged husband's family a beef wellington laced with death cap mushrooms, killing three and attempting to kill a fourth. 

1News Australia correspondent Aziz Al Sa'afin says media from around the world have been covering this case ahead of the verdict.

"There's been 125 pieces of evidence that have been put forward to the jury, they've had to analyse an 86-page chronology of the testimony that's happened over the last 10 weeks - so as you can imagine, there's a really big responsibility for this jury to get it right."
