SNAPSHOT OF A MURDERER - ALEXANDER VILLALUNA:
Alexander Villaluna, 45, a nurse from Sydney has been sentenced to at least 30 years in jail.
Wounding with intent to cause grievous bodily harm and murder.
Villaluna stabbed his ex-partner, Jovi Pilapil, then 38, and killed her Tinder date, 53-year-old Keith Collins, at a Hornsby restaurant on March 30, 2016.
He was arrested at the scene, holding a hunting knife and sitting in a chair beside Mr Collins' blood-covered body.
He told police he didn't know the deceased man but repeatedly stabbed him because "he was with my wife".
He pleaded guilty to both offences before trial.
Justice Robert Beech-Jones said the attack was "savage, cowardly and undertaken without hesitation".
Villaluna was a "textbook example" of a domestic violence perpetrator who attacked Ms Pilapil and Mr Collins because of his "twisted belief that she was his property".
"His victim did nothing more than meet a woman for a dinner date," the judge said.
Forty years in jail with a minimum term of 30 years.
