THE former partner of murdered Bundaberg woman Roxane Gilbert says her daughter Matilda Gilbert should not be justifying the actions of her brother Horace Lorenzo Jones, 21, who was this week found guilty of Ms Gilbert's murder.
Roxane Gilbert was attacked with a samurai sword and steak knife in Gladstone on June 29, 2012.
Her body was found with 25 wounds.
Jones was sentenced to life imprisonment after the jury found him guilty in the Rockhampton Supreme Court on Tuesday.
Michael Hunter, who has a six-year-old son with Ms Gilbert, spoke to the NewsMail after Matilda said the sentence imposed on her brother was "really tough".
"Horace needs to take full responsibility," Mr Hunter said. "Roxane just wanted the best for her kids.
"Roxane was frustrated at Horace's heavy cannabis use. (She) would get upset but she didn't deserve what she got."
Mr Hunter parted ways with Ms Gilbert in early 2011 after a four-year relationship.
He said nothing justified what Ms Gilbert went through.
He said Ms Gilbert suffered bipolar disorder and post traumatic stress disorder as a result of a traumatic life in South America, but above all else, she loved her children.
Mr Hunter said Ms Gilbert was a real victim and any attempt by Matilda and Jones to claim otherwise was not right.
"If the system failed anyone it failed Roxane," he said.
"Matilda and Horace's life was a walk in the park compared to Roxane's."
Mr Hunter said Matilda had "no right" to assume she had the support of her six-year-old-brother, Mr Hunter's son.
"She's only seen him three times since I separated with her mother over a year before her death."
Mr Hunter said Ms Gilbert's death could have been avoided if Jones chose to walk away that night, but instead he made the decision to attack her and he needed to stop blaming anyone else.
