A Qatari man was today sentenced to life in jail with a minimum of 15 years for the ferocious, jealousy-fuelled murder of his lover's long-term partner in a Subiaco unit.
In November last year, a Supreme Court jury convicted Mohammed Ahmed Almansouri, 39, of murdering Texan man Kenneth "Kenny" Horack by stabbing him 14 times in a jealous rage on August 4, 2011.
Almansouri's boyfriend Ben Campbell was Mr Horack's partner of 17 years.
Mr Horack was visiting from the US and all three men were living at Mr Campbell's unit.
The court was told Almansouri had become increasingly jealous and insecure about his relationship with Mr Campbell, which had been fuelled by Mr Horack's taunting and demeaning attitude, which included describing his eventual killer as just a "houseboy".
The jury rejected Almansouri's claim he acted in self defence.
He became enraged after realising Mr Horack, who had only been in Perth for nine days, had replaced a photograph of Almansouri and Mr Campbell with another one of Mr Horack and Mr Campbell in the living room.
He grabbed a knife and attacked Mr Horack, who bled to death.
Justice Lindy Jenkins said all three men should have had the sense to know better and end the living arrangements.
She said while the incidents that fuelled jealousy between the love rivals were outwardly minor, including sleeping arrangements, to them they were like "red rags to bulls".
She accepted there was a degree of provocation, but said Almansouri's extreme response was unjustified and unreasonable.
"You attacked an unarmed man ferociously and repeatedly. You took Mr Horack's life simply because he claimed a closer relationship than you with Mr Campbell," she said. "The offence was caused by your jealously and insecurity."
Justice Jenkins said Almansouri and Mr Campbell maintained a relationship despite Mr Horack's murder. She said Mr Horack's two sisters had described the immense loss of their brother and how they would never heal from the injustice.
She said Mr Campbell told the court how his life had been turned upside down with the loss of his long-term partner and the involvement of his new partner.
The judge said she imposed a lower minimum term because Almansouri faced a harder time in custody than other prisoners because of language barriers and being isolated from his homeland, family and friends.
Justice Jenkins accepted Almansouri had some remorse, but it was not complete because he still failed to accept full responsibility for the murder.
She said Almansouri was not naturally a violent or aggressive person.
"I'm satisfied your murderous intention was short-lived and soon after the attack you regretted your actions," she said.
She accepted Almansouri did not intend to kill Mr Horack, but intended to cause him life-threatening injury.
Prosecutor Laura Christian said the attack was "brutal" and "persistent". She said it was "callous" that Almansouri left the unit after the attack, not knowing if Mr Horack was alive, and took his victim's phone with him. She argued Almansouri did not show proper remorse, saying his immediate concern was the effect the attack would have on his relationship with Mr Campbell.
The court was told Almansouri rang Mr Campbell at a work dinner, hysterically telling him: "I killed Kenny."
Defence lawyer Laurie Levy argued there was provocation in the lead up to the attack in which Mr Horack made his client feel like his relationship with Mr Campbell was meaningless and the attack occurred in the heat of the moment while Almansouri was intoxicated.
He said in his victim impact statement, Mr Campbell stated that Mr Horack had anger management issues and was provocative towards Almansouri. He said there was a violent struggle and the crime scene had "resembled something like Cyclone Tracy".Almansouri's earliest release date is 2026.
