A FIVE-month pregnant woman who was found dead with her boyfriend’s head allegedly spiked on a stick has been named.

Athena Georgopoulos, 39, was allegedly killed alongside her 50-year-old partner Andrew Gunn – with chilling graffiti scrawled outside their property.

Cops dramatically swarmed the property in Melbourne, Australia, on Monday night after a neighbour heard yells and alerted police.

Police allegedly discovered the man’s decapitated corpse beside the dead woman inside the Adrienne Crescent property in Mount Waverley.

A 34-year-old homeless man was then arrested shortly afterwards at Westall train station in the early hours of Tuesday – but he has not been charged.

The station is just 6km from the small property where the couple were found.

Detectives are now probing if the graffiti outside the home is linked to the horrific scene found inside.

The messy graffiti included derogatory and aggressive phrases like “U R Gay”, “Enough is Enough”, “Betrayal” and “Karma”.

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

Detectives revealed the man in custody is being quizzed over the deaths.

They also said the man was known to the dead pair, only one of whom lived at the small property.

Athena was five months pregnant when she died and was in a relationship with Andrew before they were allegedly murdered.

The couple’s next of kin have been informed and post mortems will be held on Wednesday.

Athena’s aunt Patty Dilveridis told the Herald Sun her niece never thought she would be a mum.

“She was so looking forward to having a baby, because she was 39 [and] she never thought she could have one,” she said.

Meanwhile, her mum Petty, who was being looked after by Athena, was left “devastated”.

Cops are still working to establish a link with the man in custody.

Detectives also said they are not looking for anyone else in connection with the case at this stage.

They said a weapon was used in the alleged murder – but confirmed it was not a firearm.

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

The motive for the alleged killings remain unknown – but local media have reported the case may be drug-related.

Detective Inspector Dean Thomas from the Homicide Squad said police: “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.

“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.”

He added: “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.”

A spokesperson for Victoria Police said: “Police are aware of graffiti on the property in Mount Waverley where the bodies of two people were located last night.

“Homicide Squad detectives will work to determine if the graffiti is relevant to the murder investigation.”
