FROM the outside, it looks just like any other Glen Waverley family home.
A car with a baby seat is parked in the driveway and a pair of sandals sit on the doorstep. The only sign of anything amiss is the newspapers beginning to pile up on the letterbox.
Just days ago police uncovered a horrific scene inside - a family of four found dead, two children and their parents.
Neighbour Peter Kardis says he couldn't believe it when told by police what had happened.
"It's just so hard to comprehend. I only saw them on Saturday."
He says the family had lived in the Marcia Court home for six years and he would always greet them whenever they were outside.
"The father would mow the lawn, wash the car and the children would play with their father," he said.
Last December, the family was involved in a fiery single-car crash in Sassafras and both parents were injured. Police will investigate whether there were any relationship issues between the parents and the background to the car crash.
Mr Kardis said that after the crash he saw the wife in a neck brace and people coming and going from the house.
Eighty-two year-old Kath Ashman, who lives at the top of the quiet cul-de-sac, said she didn't see the family much after the accident because they were often going to hospital.
"The kids were lovely. They seemed very happy, always happy."
Mrs Ashman says she only learned of the tragedy when a friend rang to tell her three people had been killed in the street. "She then rang back and corrected herself, told me it was four people.
"I didn't know exactly what happened until the next day when police told me."
She and neighbours were sick of people "stickybeaking" at the house after it made front-page headlines.
Post mortems were carried out last week. Victoria Police say the investigation is ongoing and at this stage they are not looking for any third party.
The homicide squad has passed the investigation to the Monash crime investigation unit, which will prepare a report for the coroner.
