A Melbourne jury is still grappling with the decision on whether Bourke Street murder-accused James "Dimitrious" Gargasoulas is mentally fit to stand trial.
The 28-year-old is accused of running down pedestrians in the city in January 2017, killing six people, including two children.
A Supreme Court jury of 12 continued deliberations on Wednesday as they try to reach a unanimous decision after retiring on Monday.
They told Justice Lex Lasry on Tuesday they were struggling to agree but the judge sent them back to continue talks, urging them to listen to others.
The jurors have so far spent about 15 hours deliberating and they will continue on Thursday.
The defence argues Gargasoulas is "profoundly psychotic", believing he is the "Messiah" sent to save the world from a comet, and should not stand trial.
But prosecutors say he should stand trial, arguing he understands his case and the trial process.
Medical experts in the case have been divided over the question of Gargasoulas' fitness.
Two psychiatrists believe he is unfit for trial but one psychologist disagrees.
