A man who stabbed a love rival to death during a fierce brawl on a Scarborough driveway has been jailed for ten years for manslaughter at WA's Supreme Court.
Luke Anthony North, 51, will have to serve a minimum of eight years behind bars for the unlawful killing of Christopher Evans on the driveway of a unit in Gildercliffe Street in Scarborough in September, 2012.
North had been tried for murder, but a jury instead convicted him of the lesser charge of manslaughter after they heard about the brawl between the two men.
They had both been vying for the affection of Mr Evans' wife Lisa, who the court was told was in an on/off relationship with North and was working as a live-in carer for her elderly mother.
The fight began after Mr Evans and his wife returned to the Scarborough unit after a day out, and North confronted the 47 year-old plumber.
The court heard that after a verbal stoush, Mr Evans grabbed a crowbar from his van and North retrieved a 20cm kitchen knife from inside.
After being hit once with the crowbar by Mr Evans, a blow which broke his collar bone, North stabbed his victim in the chest three times - with one wound found to be 18cm deep.
Justice Lindy Jenkins said that North's response during the fight had not been reasonable, saying a blood trail showed Mr Evans had been retreating as he was being stabbed.
"The severity and number of the injuries indicates you meant to inflict life threatening bodily injuries at the very least," she said.
"You took a very dangerous knife into an already volatile situation."
North was jailed for ten years, and will be eligible for parole in September 2020.
