Bizarre twist as detectives hunt for mysterious yellow car after husband and wife are found dead in unit following angry argument and ‘blood-curdling scream’

A man and a woman found dead in a house in a Melbourne beachside suburb were seen arguing outside before the tragedy.

Witnesses told reporters at the scene that they approached the feuding couple around 11 a.m. Thursday in an attempt to “ease the tension.”

It remains unclear how the pair died, with Detective Inspector Scott Dwyer revealing little more than that the deceased were known to each other.

Other witnesses claimed to have seen and heard a vehicle speeding away from the scene shortly after the pair were believed to have been killed.

Ange Notta told it Herald Sun Just before the grim discovery, he heard a car speeding from the street.

‘I heard a car, it just turned off, which was unusual. “I just thought it was someone leaving the street in distress,” he said.

“I just heard the car and screeching wheels.”

Mr Notta claimed detectives asked neighbors if they had noticed a yellow Volkswagen in the area.

However, they later said the car was not involved in the tragedy.

The pair were discovered just before 11am on Thursday at a property on James Street in Mordialloc, in the south-east of the city.

Photos from the crime scene show SES crews assisting police as a crime scene was established on the residential street.

The couple has not yet been formally identified.

Neighbor Jade Lindsay said she heard a ‘blood-curdling scream’ from a ‘very distressed’ woman who had discovered the bodies.

“It was a very disturbing, blood-curdling scream that really scared me because it lasted so long,” she told the newspaper Herald Sun.

“It’s quite disturbing to hear… that lady who was shouting was clearly very upset.”

Ms Lindsay said a man and a woman, believed to be in their 30s, were walking up and down the pavement outside the house.

She saw the man stop and put his head in his hands.

Victoria Police said they are not looking for anyone else in connection with the deaths.

“The circumstances surrounding the deaths have yet to be determined,” police said.

‘Officers have cordoned off the area and a crime scene has been established.’

There is no threat to the community.
