An Australian man has been sentenced to life imprisonment for the murder of New Zealander Alisha Lauren Hendren-Krippner in Perth.
Tobias Marcus Nuttall, 33, admitted to the fatal stabbing of the 30-year-old at her home in August 2025. He will be eligible for parole after 18 years.
Western Australian Supreme Court Justice Amanda Forrester told Nuttall he had attacked Hendren-Krippner "in a vicious and completely uncontrolled manner". She said he had "not only taken Alisha's life ... but you have been responsible for shattering the lives of countless others".
The victim sustained nine stab wounds to her neck and body and died in hospital. Police found Nuttall at the scene with blood on his hands and a 25cm dagger after he called emergency services.
Hendren-Krippner's father Calvin Krippner told the court "Alisha was my daughter, my pride and my joy" and that "a father should never have to bury his child". Her mother Anita Krippner described the sadness as "overwhelming".
The court heard the killing followed a dispute over a rent inspection. Nuttall claimed Hendren-Krippner picked up the knife during an argument, but Justice Forrester said she could not determine exactly what happened.
The pair had recently returned from Sydney where they used drugs and argued as their relationship broke down. Nuttall had methamphetamine in his system and was likely coming down from the drug when the attack occurred.
Justice Forrester rejected defence claims that Nuttall was genuinely remorseful, saying he had tried to rationalise his actions rather than take full responsibility.
