Child model Amy Everett, who was once the face for the iconic Australian outback hat firm Akubra, killed herself after being a victim of cyberbullying. The 14-year-old died on Jan. 3, but the news of her death came Tuesday.

In a heartbreaking Facebook post, Amy "Dolly" Everett's father said his daughter had taken her life "to escape the evil in this world." To raise awareness about cyberbullying, Amy's father invited everyone who trolled his daughter online to attend her funeral. Everett's father Tick did not give any details of the harrowing experiences that had tortured his daughter.

"If we can help other precious lives from being lost and the suffering of so many, then Doll's life will not be wasted," he wrote. "If by some chance the people who thought this was a joke and made themselves feel superior by the constant bullying and harassment see this post, please come to our service and witness the complete devastation you have created."

Hat company Akubra also expressed its condolences, issuing a call for all to "stand up" against any kind of bullying.

"To think that anyone could feel so overwhelmed and that is their only option is unfathomable. Bullying of any type is unacceptable," the Akubra post said.

On Wednesday, the family released a statement saying their daughter was "the kindest, caring, beautiful soul... She was always caring for animals, small children, other children at boarding school who were less fortunate than herself."

The family also shared a recent drawing by Dolly that shows a skinny figure bent over backwards, underneath the words: "Speak even if your voice shakes."

Her family said: "This powerful message tells the dark, scary place our beautiful angel had travelled to."

According to the BBC, one in five children in Australia have said that they were bullied in the past year.

While Australia's National Centre Against Bullying (NCAB) says that overall bullying rates have marginally declined over the past decade, cyberbullying has witnessed a sharp increase.

"What's different in the case of cyberbullying is that it can be constant, 24/7," Jeremy Blackman of the NCAB told the BBC. "Another big factor is the anonymity on the internet," he said.
