AFTER years of hostility between Zarko Ilic and his stepfather, one allegation of family abuse finally brought the animosity to a fatal boiling point.
Ilic's relatives have told the Supreme Court, where Ilic is on trial for murder, of seeing a knife-wielding Ilic and bloodied stepfather in September 2009.
Ilic has pleaded not guilty to stepfather Ivan Martic's murder.
Ilic's half-brother, Dario Martic, told the court his father and Ilic did not talk and ignored each other despite living in the same Goodna home.
He told the court he was in the shower on September 29, 2009, when he heard a struggle between two people.
Mr Martic went downstairs into the kitchen and saw Ilic and his mother.
"Mum was crying standing in front of Zarko and I saw Zarko holding two knives," he said.
"He saw me and I got scared so I went back up the stairs to get the car keys and go to the police station."
The court heard Ilic's stepfather had allegedly been complaining that Ilic's maternal grandmother, who also lived in their home, did not pay any bills before switching the power off.
Mr Martic confirmed his mother said she paid the bills and turned the power back on.
The jury was shown a video interview of another relative, who cannot be named for legal reasons, giving evidence about the alleged stabbing.
The teen confirmed Ilic had learnt his stepfather had hit his grandmother a few months prior.
He said he saw Ilic saying he wanted to kill himself while holding two knives from the kitchen.
He allegedly saw Ilic's stepfather lying on the ground with blood on his face.
"I left because (Ilic's mother) was screaming really loudly," he said during the police interview.
"I went and grabbed some water as her face was really red from all the screaming."
The trial continues.
