Investigators continue to attempt to find out if the double death reported in Sydney on Sunday afternoon was a murder or a suicide.

In the afternoon, a male relative discovered the dead bodies of a man and woman at their house on The Horsley Drive in Smithfield. The bodies were found in the bathroom at around 12:30 pm on Father’s Day while a four-year-old girl was found sleeping in another room of the place. The girl remained unharmed, and after the recovery of the dead bodies, NSW police took the girl away in an ambulance.

Reports state that police have been noting down the incident-related details to prepare a report for the coroner to take over the case. The NSW police department has also urged the public to come forward and provide information if they have any relating to the incident that occurred inside the rented weatherboard residence.

“Investigations by Fairfield Local Area Command with assistance from the Homicide Squad are in their infancy, and detectives are continuing to make inquiries to determine what has occurred,” police said in a statement.

Investigators are still trying to find out if the double death was a result of murder or suicide.

Following the police’s interrogation with the neighbors, the officers found that the couple had broken up recently, and the mother and daughter shifted from the Smithfield house. A neighbor provided her a small toy to play with when the emergency services arrived at the murder-suicide spot.

“She has been gone for months,” a neighbor said as quoted by 9News. “She took the daughter with her, so I was surprised to see her car there today. It’s so sad, she is such a smart little girl. They didn’t harm her, thank God.”

The Sydney Morning Herald reported that there were several work vans parked outside the double death spot in Smithfield, which indicated the man had his own business.

The officers have urged the public to help in the investigation and call Crime Stoppers at 1800333000 for any related information.
