It has been eight years since 30-year-old father Bradley Hugh Hoddy vanished after saying goodbye to two mates at Warwick Grove Shopping Centre in August 2006.
Police believe the then 30-year-old went to the northern suburbs to meet someone he knew and was later murdered.
Mr Hoddy’s grieving former partner Victoria Medlicott, the mother of his two sons, has again appealed for information about his fate as his family mark another year without him.
“We just want answers,” she said. “It would give us closure and let us move on, it would mean everything.”
Ms Medlicott said their two sons were really upset and wanted to know what had happened to their father.
“I’ve only recently told them that he passed away… a very difficult thing for them to understand,” she said. “Obviously they missed out on a lot, especially my youngest son - he doesn’t have any photos with his father.”
Mr Hoddy adored his elder son, now nine, but disappeared in the months before the birth of his second son.
Both boys keep asking their mother if they can put up posters to help find their missing dad.
Major crime squad Det-Insp Gene Pears said Mr Hoddy’s family and friends deserved answers.
“People out there are well aware of what’s happened and we’re encouraging them to come forward to assist us and to help his family,” he said.
“Tragically, this week marks the anniversary of this young father’s untimely death and we need the public’s help to bring closure to this matter.”
Mr Hoddy was last seen alive about 5pm on August 4, 2006, when he left his two friends at the shopping centre.
Homicide detectives say they believe he rode a motorbike to the northern suburbs later that evening to meet someone but have provided no other details.
They are trying to trace his movements in the hours after he left the shopping centre.
Police revealed in February they were treating Mr Hoddy’s disappearance as a suspected homicide.
