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 awoken victim who chased after three boys before a scuffle ensured and the accused allegedly stabbed Dr Gordon six times, killing him on the street.

The jury heard evidence from one of the other teens involved in the incident about what occurred after Dr Gordon caught up to them outside a driveway in his car.

The boy said he and the other teen jumped over the driveway’s fence, leaving the accused, but they both jumped back after hearing him yell for help.

“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.

“Ash kind of just collapses completely on the ground and stops moving.”

The trio then ran away to a trail where the witness said the accused allegedly told him how he “yinged” (stabbed) Dr Gordon.

A day after the incident, the teen witness told the court he had a phone conversation with the accused and the third boy where 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 trial.

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”.

The boy said he had been texting other friends during the phone call, who told him to “stay and deal with the consequences”.

“Then I heard (the accused) tell me to come to them and run away with them,” he said.

The witness told the court he said “goodbye to my family” and met up with the two teens in their apartment in Melbourne’s inner-south-east just after midnight on January 15, where he alleged they “weighed up all options”, including throwing away SIM cards.

He returned home later that evening.
