THE REAL ERIN PATTERSON EXPOSED!

Her true colours are revealed as her 11-week trial ends

- 

As Erin Patterson prepares to face sentencing after being convicted on three counts of murder and one count of attempted murder last week, many who knew the Mushroom Killer are starting to open up about what she was really like.

"She was quite aggressive in the way she spoke to people," a former colleague who worked with Patterson as an air traffic controller in the early 2000s revealed to the ABC.

"She wasn't necessarily always unpleasant to be around but you tended to be wary that she could snap or say something unpleasant at the drop of a hat."

Another colleague described Patterson, 50, as a strange loner who was the only one in their group who rejected all invitations to social activities.

But no one could have predicted Patterson would become a mass murderer.

THE VERDICT

After a week of deliberation, the jury on the Supreme Court trial found Patterson guilty of killing her ex-husband Simon's parents Don and Gail Patterson, both 70, as well as Gail's sister Heather Wilkinson, 66, with a death cap mushroom-laced beef Wellington.
