Police are investigating the gruesome murder of a couple and their daughter in South Australia after their son heard about the deaths via Facebook.
Teenager Chantelle was found dead alongside her parents
The bodies of Andrew and Rose Rowe and their 16-year-old daughter Chantelle were found in a house in Kapunda, near Adelaide.
They had suffered multiple injuries and local media reports say officers found a large amount of blood inside the property.
Mr and Mrs Rowe's son Christopher was on holiday in Queensland at the time and heard that bodies had been found in the street where they lived.
He used Facebook to ask friends for information.
"Can someone tell me what's going on? That's my parents' street," he wrote on his page on the social networking site.
"My family lives on that street and I can't get through to any of them."
Christopher heard bodies had been found in a house on his parents' street
He was initially told it was not his parents' house that was
involved, but the police then got in touch to confirm the tragic news.The bodies were discovered on Monday and after examining the scene detectives confirmed they were looking for one or more killers.
Detective Supt Grant Moyle said "I ask the public to be vigilant in their safety.
"There are many unknown aspects of this scene and the examination and processing of the scene is going to take some time.
"This is a small community and I'd also ask if any member of this community or others passing through the area saw anything unusual in the township or on the roadways to and from Kapunda to contact police as soon as possible."
The Adelaide Advertiser reported that police have found a trail of blood outside the house and have been searching nearby properties for other clues.
