Neighbours said they heard screams and spotted a flaming jerry can at the Cranbourne property on Saturday night before the 22-year-old was taken to the Alfred Hospital, where she died today.

A 29-year-old man who is known to the victim has been questioned by police about the incident, but no charges have been laid.

A spokesman for Victoria Police said: “The exact circumstances regarding the incident are still to be determined and the matter is being investigated by the Homicide Squad with assistance from the Arson and Explosives Squad.”

“They’re a pretty quiet bunch. You never really hear any noises or hear any disturbances,” a neighbour told 9 NEWS on Sunday.

Another neighbour, Daniel McCreedy, told Nine News he found the woman burnt after hearing loud screams.

“It was quite distressing. We found a jerry can in the backyard on fire, which we put out, and then just proceeded to try and look after them,” he said.
