In a shocking incident in Melbourne’s southeast, it is alleged that a man was decapitated, with his head gruesomely placed on a stake next to the body of his deceased partner, who was five months pregnant, on Monday.

Sinister graffiti was also found scrawled outside the Mount Waverley unit where the couple were allegedly murdered.

Heavily armed police swarmed the Adrienne Crescent property at 9.55pm on Monday after a neighbour heard yells and called triple-0.

Authorities reportedly found the man’s mutilated remains beside the woman’s body inside a unit in Melbourne’s southeast, but the identities of the two victims have not yet been officially confirmed.

A 34-year-old homeless man, accompanied by two large dogs, was taken into custody shortly after at Westall train station around 1:40 am on Tuesday, though no charges have been filed at this time.

The station is just 6km from the small cream-coloured unit.

Investigators are currently examining whether the graffiti outside the scene, which includes messages such as ‘U R Gay’, ‘Enough is Enough’, ‘Betrayal’, and ‘Karma’, is connected to the disturbing events discovered inside.

The apparently threatening messages were daubed on the walls in luminous yellow-green and black spray paint, as well as on the property’s fence.

Ominous graffiti marked the exterior of the Mount Waverley unit where the pair were reportedly killed, as homicide detectives investigate the crime scene.

Police are probing whether the graffiti is connected to the alleged murders, with multiple crime scene investigation officers on the scene

Police are probing whether the graffiti is connected to the alleged murders, with multiple crime scene investigation officers on the scene. 

Detectives have now revealed the man in custody is being quizzed over the deaths and was known to the dead pair, one of whom lived at the small unit.

Police identified the dead woman as a 39-year-old from Mount Waverley, while they said the man is believed to be 50 and also from Mount Waverley. 

It was revealed the pair had been in a relationship and the deceased woman was five months pregnant when she died. 

Their next of kin have been informed and post mortems will be held tomorrow for the dead pair. They are still trying to establish a link with the man in custody.

Detectives said they are not looking for anyone else in connection with the incident at this stage, but said a weapon, although not a firearm, was used in the alleged murder.

The street has been cordoned off by police as homicide detectives continue their investigation. 

The motive for the alleged killings are unknown but it has been reported drugs may be a reason.

Heavily armed police swarmed the Adrienne Crescent property at 9.55pm on Monday after a neighbour heard yells and called triple-0 

Police allegedly discovered the mutilated body of the man and a woman inside the unit in Melbourne’s southeast but pair have yet to be formally identified 

Detective Inspector Dean Thomas from the Homicide Squad said police received several calls regarding the incident at the address prior to the grim discovery. 

‘Police were called at about 9.20pm in relation to a welfare check at the address based on some yelling that was heard from the property,’ he said.

‘A second call was then made that suggested it was perhaps more urgent than the first call and police arrived minutes later, and obviously they found the male and female inside the premises deceased.’ 

Det Insp Thomas said heavily armed specialist officers, assisted by the police helicopter, tracked the arrested man to the station, where he was taken into custody. 

‘The person that we took into custody was in the company of two large dogs, I think that would look fairly obvious to people who may have been in the area,’ he added.

Det Insp Thomas added forensic crews and investigators would be at the scene most of the day, and counselling was being offered to those living in neighbouring units. 

One neighbour said he did not know the people at the house and had never heard of any trouble or police attending the unit prior to last night. 

‘It’s a quiet area,’ the man said.

A Victoria Police spokesperson confirmed investigators were probing the graffiti.

‘Police are aware of graffiti on the property in Mount Waverley where the bodies of two people were located last night,’ the spokesperson said. 

‘Homicide Squad detectives will work to determine if the graffiti is relevant to the murder investigation.’
