A father who called triple-0 to tell police his wife and three young children were dead inside their family home appeared 'extremely distressed' as he waited on his front lawn for paramedics to arrive.
Emergency crews were called to the house on Burgess Street, Tullamarine, in Melbourne's north west, about 12.30pm on Thursday.
There they found the bodies of 43-year-old Katie Perinovic and three children - Claire, seven, Anna, five, and Matthew, three.
The 48-year-old father of the children, Tomislav Perinovic, is a 'person of interest' and is assisting police with inquiries. He is yet to be formally interviewed.

'We have a long way to go before we can actually understand and appreciate what occurred.'
