A Perth teenager is facing a possible life jail term after being found guilty of murdering a stranger during a confrontation over a bike he had stolen from a 10-year-old boy.
The teenager, who cannot be identified, was 15 in May last year when he used an 18-centimetre filleting knife he was carrying to stab 42-year-old Petr Levkovskiy in the abdomen, on a Sunday morning in the southern Perth suburb of Bull Creek.
