Officers found Mr Cady dead on the bedroom floor of his New Dapto Road apartment about 5pm.

A homicide investigation is underway into the cause of Mr Cady's demise, with police saying on Saturday forensic clues indicated his death was ‘‘very clearly suspicious’’. 

The investigation has been hampered by the days-long gulf between death and the discovery, which resulted in an ‘‘advanced state of decomposition’’ to the body, police said.

A forensic examination of the New Dapto Road apartment and a postmortem in Sydney were ongoing on Sunday.

However police had established ‘‘very strong lines of inquiry’’ after interviewing residents of the complex and its neighbours, Wollongong Superintendent Kyle Stewart told media during a briefing on Saturday.

‘‘From the preliminary forensic investigation we have to hand at this point in time, we’re quite comfortable as to where our investigation’s going to take us,’’ he said at the press conference.

‘‘One of the things that is unknown is the cause of death ... but the obvious forensic evidence we have ... absolutely leaves us in no doubt that this man’s death is a suspicious death.’’

Mr Cady’s brother-in-law lived in an apartment within the same complex and contacted police after noticing his absence.

Mr Cady was known to police and fingerprints were used as part of the process of identifying him. 

The New Dapto Road apartment complex is managed by Illawarra Housing Trust and is well known to police.

‘‘It’s one of those locations that often has people that need our help,’’ Supt Stewart said.

There were no obvious weapons in the immediate vicinity of Mr Cady’s body. 

The homicide is the subject of a strike force investigation.

Police are calling for members of the public with knowledge of the incident to come forward.

‘‘Whist we have very strong lines of inquiry ... there is much we don’t know,’’ Supt Stewart said.

‘‘It is sadly the fact that he had gone unnoticed for a number of days. By the time we got to him his body was in a state of advanced decomposition, which has hampered our inquiries to a degree.’’
