Woman who killed abusive ex faces sentence

A Sydney woman who killed her abusive ex-partner on Mother's Day three years ago is due to be sentenced.

Jessica Silva stabbed her estranged partner James Polkinghorne to death after he showed up at her family's Sydney home, in the inner western suburb of Marrickville, in 2012.

A jury last year found Silva not guilty of murder but guilty of manslaughter.

Over the course of her trial, the court was told that Silva's four-year relationship with Mr Polkinghorne had been marred by physical and verbal abuse.

In one text sent to Silva on the day he was stabbed, Mr Polkinghorne wrote: "I hope your mother gets poisoned by the flowers that you give her and you get gang-raped."

Silva is set to face sentencing proceedings in the NSW Supreme Court on Friday.
