Western Australia massacre victim's chilling poem before killings

A chilling poem written by an Australian mother who was killed alongside her children has resurfaced - highlighting her struggles with domestic violence.

Katrina Miles, and her children,13-year-old daughter Taye and sons Rylan, 12, Arye, 10, and Kadyn, 8 were all found dead at a private property in Osmington near Margaret River in Western Australia on Friday (local time).

It is believed Ms Miles' father Peter Miles, 61, killed them and his wife Cynda before turning the gun on himself. 

Domestic violence support group The Red Heart Campaign has since shared a poem written by Ms Miles in 2014.

The poem titled "I'm battered not broken" details domestic violence from the perspective of her and her children. 

"The echo of my shouts, the thump of my dignity slammed against a wall," she wrote. 

"Paste those fake smiles, quick hurry quick hurry quick hurry.

"Shh shh child.

"Please, please, please be good.

"Be calm, be still.

"Make it easy."

Ms Miles talks about the need to obey despite hating the word obey and said she wanted to break free.

"I asked God to save me and he was there.

"I asked myself to save me and yet I could not.

"I look into my only daughter's eyes.

"I look into my three sons and I can."

She said she would leave and return to the home because she had to save her children.

The Red Heart Campaign's founder Sherele Moody told News.com.au the shooting needed to be treated as a domestic violence incident.

Police are treating the massacre as a murder-suicide, and the investigation into why and how seven family members were killed is expected to take some time.

It's Australia's deadliest mass shooting since 35 people were killed in Port Arthur, Tasmania in 1996.
