A boy accused of a doctor's stabbing murder planned to carry out more home invasions interstate and charter a plane to escape overseas, a jury has heard.
A 17-year-old boy, who cannot be named for legal reasons, is standing trial in the Victorian Supreme Court after pleading not guilty to the stabbing murder of GP Ash Gordon.
He has admitted two counts of aggravated burglary.
The boy was allegedly one of four teenagers who had broken into Dr Gordon's suburban Melbourne home twice in the early hours of January 13, 2024 to steal items as the victim and his housemate slept.
The teens were caught on their second entry by the woken Dr Gordon who chased after three boys before a scuffle ensured and the accused allegedly stabbed him six times.
The jury heard evidence on Friday from one of those being chased that the accused had yelled for help after Dr Gordon caught up to them outside a driveway.
"I saw Ash stumbled over on the ground. (The other teen) ran over to him and kicked him in the face," he told the court.
The trio then ran away to a trail where the witness said the accused told him how he "yinged" (stabbed) Dr Gordon.
The teen witness told the court he had been in contact with the accused and the third boy next day, when the pair said they wanted to leave the state.
"They said they were going to steal a car, go up to the Gold Coast and get a charter plane to go to Papua New Guinea," he told the jury.
Under cross-examination, he said the accused was "planning on doing more home invasions" on the Gold Coast before fleeing overseas.
The witness said the pair told him about consequences he would face if he stayed, including how he was "the prime suspect" and would "go to jail for a long time".
Defence barrister Amelia Beech has submitted the accused was acting in self-defence and asked the witness about hearing Dr Gordon saying "hello boys" after catching them inside his home.
The boy agreed with her that the voice was "aggressive" and "scary".
He also agreed that Dr Gordon, chasing three "panicked" teens in his Mercedes, had been driving fast and they could hear "aggressive revving" moments before the boys ran into a driveway to escape.
The witness said he felt "stressed", "panicked" and "terrified" and was worried what the GP would do to him and the others.
He heard the accused say "don't bro, stop" multiple times before the stabbing, the court was told.
The trial continues.
