Jury to begin deliberations on Abdallah

The jury in the murder trial of Katherine Abdallah are set to start deliberations on Thursday morning.

The 33-year-old has pleaded not guilty over the fatal stabbing of her flatmate Suzie Sarkis on the ground of self defence.

Sarkis, 21, died from a chest wound sustained during a fight with Abdallah at their Brighton-Le-Sands townhouse on February 9, 2013.

In summing up the arguments put before the jury during the trail, Supreme Court Justice Christine Adamson said the defence had argued that the crown hadn't proved beyond reasonable doubt that the act wasn't self defence.

"Your verdict in respect of murder should be not guilty," Justice Adamson said on Tuesday, quoting remarks made by Ms Abdallah's defence lawyer Gregory Stanton.

The crown had argued that Abdullah was not acting in self defence when she attacked Sarkis with two kitchen knives, penetrating her chest by up to 10 centimetres.

"The deceased never presented a real threat to the accused," Justice Adamson said in summing up crown prosecutor Siobhan Herbert's arguments.

"The use of knives was excessive."

The court heard earlier in the trial that Abdullah had tried to blame the stabbing on a girl called "Amy" and it was only after police discovered CCTV footage from inside the unit that she claimed self defence.

Following the attack on Sarkis, Abdallah called triple-zero, thoroughly cleaned the two knives and put them away, Ms Herbert said.

The eight men and four women of the jury are expected to begin deliberations on Thursday morning after Justice Adamson concludes her summing up remarks.
