Breaking: Woman in custody after 4-year old boy and 60-year old woman found stabbed to death.

A 45-year old woman is in custody after a double murder in Melbourne’s north-west. The victims were a grandmother and her four-year old grandson.

The scene that faced officers was “horrific”.

A four-year old boy, found dead, stabbed to death – also a 60-year-old woman his grandmother, stabbed to death. His 61-year old grandfather alive, but injured, found gagged and bound.

Police were called to a home on Varsity Court in Albanvale in Melbourne’s north-west early yesterday evening.

They found the deceased 60-year old woman in the backyard of the property and the man tied up.

The Age reports that police inquired about where the four-year old boy was – he was dead in one of the bedrooms.

It is believed that the boy’s grandparents cared for him every Tuesday while his parents worked.

They were not in the house at the time of the murders and are said to be “inconsolable and devastated.”

Homicide Squad detective Senior Sergeant Stuart Bailey said that the family had three other children who were not at the house at the time.

Senior Sergeant Bailey said police believed the relationship between the 45-year old woman and the boy’s grandfather may have been a motive for the murders.

He said that police believed it may have something to do with the relationship between them.

“They’ve know each other for three years. The nature of that relationship is yet to be uncovered.”

“The actual motive is yet to be established,” he said.

Police believe the 45-year-old Albion woman came to the Albanvale home some time in the morning.

It is thought that when the 60-year-old grandmother returned home she was fatally stabbed in an “altercation”.

The grandfather of the boy has been taken to hospital for minor injuries.

Senior Sergeant Bailey said “The scene is quite horrific,” he said.

“It’s quite stressful for police and crime scene services that are here.”

Neighbours relayed distressing details about the scene with some saying that the sound of whips could be heard coming from the home just before police arrived.

Nikki and Amy Brook told The Age

“Yeah, like bang, bang. It’s a bit weird,” Amy said.

“It’s scary knowing that there was a kid involved.”

The Age reports that no previous domestic violence incidents had occurred at the home.
