Former homicide squad detective Charlie Bezzina has warned the killer may strike again if he isn’t caught soon.
‘It’s imperative that those who have knowledge of some sort… assist police,’ he told 3AW. ‘This person will be known to somebody.’
'The potential is there for him to kill again. They’ve got to live with their conscience. If this person or persons strike again, they have to live with that and say could I have stopped that?'
Detective Inspector Andrew Stamper said police are treating it as a 'random attack'.
He has implored the community to contact investigators if they have any information on the whereabouts of the killer.
'Someone has come home on Tuesday night, or the early hours of Wednesday morning, maybe with blood on them, missing items of clothing, somebody knows about this and we need help,' he said.
