The man who knifed his ex-partner and brutally murdered her new date as they dined at a Sydney restaurant is beginning a 30-year prison sentence.
Alexander Villaluna's attack was "savage, cowardly and undertaken without hesitation", Justice Robert Beech-Jones said when sentencing Villaluna to 40 years in jail with a non-parole period of 30 years at the NSW Supreme Court on Thursday.
Villaluna, 45, previously pleaded guilty to murdering Keith Collins, 53, and wounding nurse Jovi Pilapil, 40, with intent to cause her grievous bodily harm in late March 2016.
Mr Collins, a divorced father of four children and three step-children, was on his first Tinder date with Ms Pilapil at the Kangan restaurant at the Hornsby Westfield shopping centre when he was stabbed 12 times.
CCTV footage shows Villaluna stabbed Mr Collins then stepped around the table to attack Ms Pilapil before returning to kneel on Mr Collins' chest as the dying man tried to roll away, so that he could stab him again.
Villaluna then calmly walked out of the restaurant.
Villaluna had been very possessive and jealous in his relationship with Ms Pilapil, which ended in November 2015, two months before she was granted an interim apprehended domestic violence order.
Villaluna will be eligible for parole in 2046.
