Tobias Marcus Nuttall was 32 when he stabbed Alisha Lauren Hendren-Krippner, 30, multiple times in her Bassendean home in August last year.<\/p>\n
Justice Amanda Forrester said Nuttall had attacked her in a “vicious, uncontrolled and completely disproportionate manner” and there was no excuse for what he had done.<\/p>\n
She said general deterrence was important because too many women were being killed by men who lost control of themselves and lashed out.<\/p>\n
Nuttall called Triple Zero and told emergency services he had stabbed Hendren-Krippner, who later died in hospital.<\/p>\n
Police found the 25-centimetre-long bloodstained dagger at the scene.<\/p>\n
The Supreme Court heard “no explanation was provided” to police by Nuttall, who later claimed he was “coming down” off methylamphetamine at the time of the killing.<\/p>\n
He pleaded guilty to murder earlier this year.<\/p>\n

Messages to father<\/p>\n
The prosecutor told the court that on the day of the murder, Nuttall and Hendren-Krippner had flown back to Perth from Sydney.<\/p>\n
At Perth airport, Nuttall sent messages to his father, claiming he had “encountered narcissism at a level that is difficult to fathom”.<\/p>\n
He also said in the messages that he was in a “fairly evil situation” and wanted to talk, telling his father he loved him.<\/p>\n
Hendren-Krippner’s parents provided victim impact statements referring to the pain and ongoing sadness of their loss.<\/p>\n
“The silence now is unbearable,” Kelvin Krippner said in his statement.<\/p>\n
Conspiracy podcaster<\/p>\n
At the time of the murder, Nuttall was a co-host of an online podcast self-branded as a deep dive “into the realms of conspiracy, the occult, magic, spirituality and everything clandestine”.<\/p>\n
“As two inquisitive minds on a quest for truth, they pull back the curtains of the mundane to reveal a world bubbling with mysteries, hidden agendas, and esoteric knowledge,” the podcast description read.<\/p>\n
Previous podcast episodes covered topics including cults, satanic rituals, demonic possession, the JFK files, Kanye West, extraterrestrial connections, and the Pyramids of Giza.<\/p>\n
A few days after Nuttall was arrested, his co-host released an episode without him saying “the podcast is not going to move forward any longer with Toby”.<\/p>\n
The co-host acknowledged Nuttall had been charged with “a very, very serious offence over in Perth”.<\/p>\n
The podcast is still active and publishing episodes without Nuttall.<\/p>\n
‘I feel vile’<\/p>\n
Defence lawyer Simon Watters told the court Nuttall had read the victim impact statements and felt a tremendous sense of guilt.<\/p>\n
Watters said his client’s words were “I feel vile, I feel regret”.<\/p>\n
Justice Forrester said it was likely Nuttall and Hendren-Krippner had used drugs the night before the murder.<\/p>\n
She said Nuttall claimed that Hendren-Krippner had “instigated” the fatal confrontation, but his plea of guilty to murder showed he was not claiming self-defence.<\/p>\n
The court heard he had claimed to have “wrestled her to the ground” and thought he stabbed her three times.<\/p>\n
Couple were separating<\/p>\n
Nuttall, who was born in WA, had been abused by a teacher when he was at school, at the age of nine, the court heard.<\/p>\n
While working at a service station in New South Wales, he was run over by a vehicle and suffered a back injury that resulted in ongoing pain and PTSD.<\/p>\n
Nuttall returned to WA in 2025 and started a postgraduate teaching course and a podcast, and met Hendren-Krippner.<\/p>\n
Justice Forrester said the couple were in the process of breaking up in August last year.<\/p>\n
She detailed Nuttall’s drug history, describing his amphetamine use as “severe”.<\/p>\n
References provided to the court on his behalf described him as “intelligent, curious, kind and loving”.<\/p>\n
Nuttall had no prior criminal record.<\/p>\n
He has to serve a minimum of 18 years behind bars, backdated to August, before being eligible for parole.<\/p>\n","protected":false},"excerpt":{"rendered":"WARNING: This story contains details some readers may find distressing.
