Body found at Sydney home that of man aged in his 30s or 40s

The backyard of a home where the mummified body of man was found wrapped in a roll of carpet will be forensically dug up as part of a murder investigation.

Police began a methodical dig on Friday morning, with sniffer dogs present, after cleaners made the gruesome discovery of a body believed to be that of a man aged in his 30s or 40s, earlier this week.

Neighbours of the house at Greenwich, on Sydney's lower north shore, revealed the house had been deserted since the owner's son died a year ago.

The Roberts family had owned the house for about 50 years, but it had been empty since Mrs Roberts died about 20 years ago.

Edna Scott, who has lived across the road for 39 years, said the son Bruce Roberts, aged in his 60s, would visit the house from time to time.

Mrs Scott said Mr Roberts' mental health declined following his mother's death.

'He was never very friendly but after she died he slowly became more and more reclusive and unkept,' Ms Scott said.

'I would wave at him when I saw him in the street - he would just stick his head down and keep walking.'

Mrs Scott said the man never lived in the property - but would visit his mum often. 

'When he was younger he would arrive on a motorbike, with a nice looking leather jacket and jeans.
