A detailed letter found​ inside teh home where ⁤two parents are suspected of killing their innocent teenage sons⁤ before taking their own lives,may hold ⁣critical answers for homicide detectives ⁣investigating the double-murder suicide.

The Clune family – father Jarrod,50,mum Maiwenna,49,and their two⁤ sons,Leon,16⁢ and‍ Otis,14 – ⁢were found dead by WA‌ Police after they⁣ were ‌called to their Mott Close property ⁤in Mosman‍ Park about 8.15am on Friday.

A ⁣person known to the family, believed to⁣ be a carer, found ‌a note on the⁣ front door ⁣which warned them to ‌not go ​inside and ⁢urged them to call police.

Both‍ boys are believed to ‍have been killed by their parents.

The family pets ⁢- two dogs⁤ and a cat‌ – were also found ​dead inside the western ‌suburbs property.

The Sunday Times has confirmed that the letter ⁤located inside the property is being carefully investigated by detectives.

It is understood they have not drawn any‌ conclusions⁣ on‍ what⁢ each parent’s role ‍was in their children’s deaths before they are suspected of taking their‌ own lives.

Police still believe their deaths were not violent and that no weapons ‍were used.

More than 32 hours after police were confronted with the highly distressing scene, ⁢it was eerily calm outside ‌the well-kept home.

Just a​ single bunch of flowers ⁤was placed on the ⁤street,⁢ a solemn tribute​ left by two ⁤neighbours clearly‌ rattled by what⁢ had transpired ‌metres away.
