A 20-year-old homeless man who brutally murdered another man with a pair of scissors in a Fremantle laneway has been sentenced to life in jail with a minimum of 18 years.
Jarrad Anthony Angliss was last month found guilty of murdering Randall Lee Duncan, 32, between Collie and Nairn streets in September 2012.
Mr Duncan was stabbed repeatedly by Angliss in what Supreme Court Justice Stephen Hall described as a brutal and sustained attack.
Justice Hall said while Mr Duncan was on the streets on the night he was killed, he was not homeless and had a home, a partner and children.
Angliss initially co-operated with police, pointing officers to the drain that contained the scissors used in the murder, but later denied killing Mr Duncan.
During the trial, defence lawyer Beau Hanbury argued Mr Duncan had been murdered by another homeless man.
In a victim impact statement, Mr Duncan's dad Ian Duncan said his son was not just another homeless person, describing the loss as painful and traumatic.
Prosecutor Linda Petrusa told the court Mr Duncan was a vulnerable and passive victim who was suffering from a debilitating disease.
She labelled Angliss' claim that Mr Duncan had slept with his girlfriend a "feeble" motive.
