What led to Corey Breceljnik's death? The questions a jury must answer

Russel Rajapakse has pleaded not guilty to murdering Corey Breceljnik and is on trial in Newcastle Supreme Court. The jury retired on Tuesday to begin deliberating.

Was it a fight between two men or an attack with a knife that led to the death of Corey Breceljnik outside a home at Watanobbi in October, 2020?

And was accused murderer Russel Rajapakse acting in self-defence after he was called to the house to recover methamphetamine stolen during a drug rip at Cessnock earlier in the night?
