A devastated neighbour of the mother and her three children who were found dead in their home in grim scenes has revealed details of a conversation he had with her less than 24 hours before her death.
It comes as forensic advisers and specialists spent “all night” methodically examining the crime scene to establish a clearer picture and to “understand and appreciate” how the “tragic event” in metropolitan Melbourne occurred.
Her husband, Tomislav Perinovic, 48, was sitting in the front yard when police arrived at the scene and was the one who called emergency services, police said.
He was still assisting officers with inquiries on Thursday night.
The homicide squad is leading the probe, but Victoria Police Acting Deputy Commissioner Robert Hill said assumptions should not be made about what had occurred inside the home.
Mr Hill said investigators were keeping open minds to a number of possibilities, including murder-suicide.
When police arrived at the scene they were greeted by Ambulance Victoria in the front yard with the 48-year-old man. Police were directed to go inside where they made the grim discovery.
Mr Perinovic has since been assisting detectives from the Homicide Squad with their inquiries while the next of kin have been notified. Police say there are no other parties involved in the deaths.
Neighbour John Constantino told The Age he had spoken to Ms Perinovic the night before she died and that nothing seemed out of the ordinary, in fact, she seemed “happy”.
“I was watering the garden about 7.30pm and she walked past and she seemed happy and everything,” he said.
“She asked me what I was going to do tomorrow, I said, ‘I might mow the lawn’ and she said ‘yeah, it’s not going to be a hot day’.”
Acting Deputy Commissioner Bob Hill said Mr Perinovic had provided police with his account of what happened and that it was “very important we do not speculate” over the events of the deaths.
When asked if police had any suspects Mr Hill declined to comment.
“At this point in time, the investigation is in its very early stages,” Mr Hill said.
“It’s very important we do not speculate. The circumstances of this event are yet to be determined.
“We cannot afford to make any assumptions as to what occurred.”
Another neighbour told NCA Newswire that Ms Perinovic would go for a walk with her children almost every day.
“She’d say hello, stop for a chat – she’s a nice lady,” he said.
“It’s really shocking.”
Ms Perinovic worked at a local physiotherapy clinic for the last seven years but according to the Herald Sun, she left the clinic “unexpectedly” three months ago.
The clinic is a 10-minute drive from the family home.
“The Herald Sun was told Ms Perinovic may have been suffering from depression,” the publication reported.
Acting Assistant Commissioner Mark Galliott said information currently indicated the Mr Perinovic was not injured.
There was no family violence history associated with this family, Mr Hill said.
Asked if it could be a murder-suicide situation, he said there were “a number of possibilities and that’s one”.
Police would not reveal details about any injuries the victims suffered.
“We just need to understand the facts, and unfortunately they’re not known to us but will be in the fullness of time,” Mr Hill said.
“We have a long way to go before we can actually understand and appreciate what occurred.”
