Missing Melbourne mum-of-three Elisa Curry closed her Facebook account and didn't use her fitbit fitness tracker in the days leading up to her disappearance, it has been revealed.
A Current Affair reported police believe the 43-year-old slept in her beach house on Saturday night before disappearing just over five days ago.
The news comes as emergency service crews scale back their search of the local area and focus on a 300 metre area around the family home at Aireys Inlet.
Victoria Police Inspector Peter Seel said the search would include empty houses, gardens and sheds with neighbours doorknocked and questioned again.
Police have said the chances of finding Curry alive after so long in the bush is 'remote' after revealing she was battling depression.
Authorities are perplexed by the disappearance of the woman who went missing from her holiday house in a small town on the Great Ocean Road.
Widespread air, land and water searches have failed to find the avid runner, who regularly jogged long distances from the property, which was again swarming with police on Thursday as the investigation continued.
'Mrs Curry suffers from depression and is reported to be an alcoholic,' a document released by Victoria Police shows.
Inspector Peter Seel told reporters it’s possible Mrs Curry went for a run and has become disoriented in bushland.
However, the likelihood of finding her alive in the bush after at least four days is remote, he added.
'Just so many days without food, water, shelter and just the elements, makes it a grim outlook', he said.
Investigators aren’t ruling out suspicious circumstances.
The last confirmed sighting of Ms Curry was by a neighbour, who saw her get into bed on Saturday night after the pair had a 'personal' conversation.
Husband David Curry and their three children watched the AFL grand final in Melbourne before returning to the holiday house on Sunday to find her missing and lodging a report with police.
Text messages on Saturday night between the couple showed no reason for concern, Inspector Seel said.
The disappearance has rocked the close-knit community.
'It’s just really scary I think because Aireys is such a small little town and it just doesn’t happen,' resident Laura Stocks told the AAP on Thursday.
