The suspected murder-suicide of an entire Melbourne family is now being investigated for links to an unexplained car crash five months earlier.
The bodies of Nilesh Sharma, his wife Pritika and their two children - daughter Divya, 3, and son Divesh, 5 - were found inside their eastern suburbs home on Tuesday morning.
Relatives had not seen the family since a weekend party, where they appeared to have been in high spirits.
Police, however, have ruled out an accident and are not looking for any suspects.
Detectives are now examining if any warning signs were present prior to the deaths, from possible marital problems to a car crash on December 29.
"It will be looked at as part of this investigation," Detective-Inspector John Potter said.
In that crash, Mr Sharma had been driving with his wife and children in the Dandenong Ranges when the car suddenly went down an embankment.
Passing cyclists had pulled the family of four to safety before the vehicle caught fire, sending all four to hospital with minor injuries.
It's not known what caused the car to suddenly veer off the road.
But Abhay Singh, an uncle of the two deceased children, said the Sharmas appeared to have been recovering well from the crash.
"They were a really lovely family," he said on Tuesday.
"It is shattering."
The two children had not been seen at school or daycare for two days, prompting calls to police to check on their welfare.
Officers discovered Mr Sharma's body in a hallway and the rest of his family dead in their bedrooms.
The Fijian Indian couple had moved to Australia more than a decade ago and lived in Glen Waverley for at least two years.
A coronial inquest will likely be scheduled once causes of death are confirmed.
