EVERY house has a story to tell. But Michael and Luwiza Bosnic reckon they would never have bought their Leppington home in Sydney's south-west if they had known of its grisly past.
For they had no idea church-going couple Anthony, 91, and Frances Perish, 93, were both found shot dead in the main bedroom of the Byron Rd home in 1993.
The Bosnics' home has now become a part of television history as the slain couple's grandkids, Anthony and Andrew Perish, feature in the fifth series of Channel 9's Underbelly: Badness.
"I didn't really know what had happened until it was too late," said Mr Bosnic, who bought the house in 1994 for $290,000.
"I was told they were deceased but they didn't tell me how. This sort of thing happens. Bad things happen."
The still-unsolved murders became part of one of NSW's biggest police investigations.
In 2008, Anthony Perish was arrested with Sean Waygood and charged with the murder of Terry Falconer in 2001.
The story of Anthony and his brother Andrew and friend Matthew Lawton, who were convicted of murdering Falconer earlier this year, is currently being played out in Underbelly Badness.
Murder disclosure laws
Under laws introduced in 2010, real estate agents who fail to tell prospective home buyers about murders or other unnatural deaths can now be hit with big fines.
The Australian Competition and Consumer Commission (ACCC) gained power to fine agents up to $1.1 million for misleading their clients.
Under the laws, if a property such as the Bosnics' Leppington home were to come on the market, potential buyers would have to be told that murder had occurred in the house.
The changes came into effect on July 1, 2010 when the ACCC merged state fair trading laws into a federal consumer protection law.
In 2004, two Sydney agents were fined $20,000 after concealing from a buyer the fact that a house had been the scene of a triple murder committed by Sef Gonzales.
