A neighbour has spoken of her shock after discovering a mother "lying in a pool of blood" next to her child.

Five-year-old, Sayagi Sivanantham, sadly died in hospital after being found with stab injuries.

Their neighbour, Elsa Gonzales, 47, said she found the pair with injuries inside a flat in Monarch Parade in Mitcham, at around 4 pm on June 30.

Police said no arrests have been made and they are not looking for anyone else in connection with the incident.

Elsa Gonzales, 47, described hearing screaming and crying coming from the flat next door, where a family-of-four from Sri Lanka lived.

Mrs Gonzales, who used to work in an emergency department, said she rushed into the flat to find the mother and child in the bedroom.

"I saw the woman lying on the floor in a pool of blood.

"There was blood everywhere.

"I looked on the bed and saw the girl, she was covered in a blanket."

Mrs Gonzales, who has lived at Monarch Parade for 12 years, added: "It's really breaking my heart, Sayagi was a smart kid, she was always smiling.

"She was a cheeky little girl, always playing with the neighbourhood kids.

"To see her so lifeless, it's like my heart is bleeding.

"She (the woman) was a good mum."

A 15-year-old Sri Lankan girl, who lives on the same block and wanted to remain anonymous, said her family were friends with the mother and child.

She described Sayagi, as "playful and talkative."

She said: "They were a happy family, we knew them for about seven years.

"We feel sad hearing the news."

An 18-year-old woman from Mitcham, who gave her name as Bethany, laid flowers at the scene this morning ( July 1).

She said: "You should always pay your respects, especially when a little child has died."

It comes a day after a man aged in his 30s collapsed in the street and died near Monarch Parade on June 29.

Police said the unrelated incident is being treated as unexplained but is believed to be non-suspicious.
