The former girlfriend of Lindt Café siege gunman Man Haron Monis has been sentenced to 44 years in prison for the murder of his ex-wife in 2013.

Amirah Droudis, who was dating Monis at the time of the attack, was found guilty last November of stabbing his ex-wife 18 times, dousing her in petrol and setting her alight at a block of flats in Sydney‘s west.

It was “a hot blooded and frenzied murder by an enraged female attacker,” Justice Peter Johnson said while delivering his verdict.

He described Monis as “an evil man” who had orchestrated the attack after a bitter family dispute, and that if Monis had not died during the siege in 2014, then he would be “sitting next to the accused in the dock.”

Droudis chose not to give evidence at her sentencing hearing last year, but her lawyers said she was repeatedly assaulted by Monis during their relationship.

She has been given a non-parole period of 33 years, meaning she won’t be released until at least 2050.
