It is now a week since a huge fire devastated the Shropshire home of millionaire businessman Christopher Foster.
The bodies of Foster and his wife Jillian were found inside the property, near Maesbrook, along with another body, thought to be their daughter Kirstie, 15.
A post-mortem examination found Mrs Foster died as a result of a gunshot wound to the head.
Detectives believe Foster killed his wife and daughter before setting fire to the property and killing himself.
Foster became a millionaire by developing insulation technology for oil rigs but his company Ulva Ltd had gone into liquidation.
A number of vehicles, including this Range Rover, were destroyed in the fierce blaze.
Floral tributes to the family have been left outside the house.
The Fosters were last seen alive when they attended a friend's barbecue on 25 August. The family went home and Kirstie is thought to have stayed up chatting online until 0100 BST the next day.
