William Barrett and Sons have urged the Greater Bunbury community to keep an eye out for an extremely valuable item.
Late last month, thieves broke in and stole numerous items - including a box containing ashes - from an Australind home.
The ashes are of Roy Edward Scaife, who had passed away in 2015. Roy's wife had planned to scatter his ashes "somewhere special".
William Barrett and Sons funeral director Adrian Barrett said the family was still in shock over the ordeal.
"Mr Scaife was a pilot, so she [his wife] had planned to scatter his ashes at the RAAF base where he learnt how to fly," he said.
"His ashes would not be very valuable to a thief, but they're incredibly valuable to her. It's heartbreaking.
"We are now calling upon all community members to keep their eyes open."
Desperate to help the family, William Barrett and Sons took to social media to express their condolences.
Over the past few weeks, the family has received an outpouring of community support.
Anyone with information about the incident or the items can contact catherinemary_scaife@yahoo.com.au or call Australind Police on 9797 0222.
