A father suspected of stabbing his three children to death died from multiple injuries, police have revealed.
Ceri Fuller, 35, was found dead in a disused quarry at a Shropshire beauty spot on Monday with the bodies of his children nearby.
A post-mortem examination concluded Mr Fuller died from injuries consistent with a fall from height.
On Wednesday it was revealed that a pathologist found that his children, Sam, 12, Becka, aged eight, and seven-year-old Charlie had died from stab wounds.
A knife was recovered from the scene at Poles Coppice on Pontesbury Hill, near Shrewsbury.
West Mercia Police said one line of inquiry was that Mr Fuller killed the children before taking his own life. The force described the deaths as a "tragic family situation" and are not looking for anyone else in connection with the deaths.
Detective Chief Inspector Neil Jamieson, who is leading the investigation, said: "The post-mortem established that Mr Fuller died from multiple injuries consistent with falling from a height."
Mr Jamieson said formal identification of Mr Fuller and his son and two daughters was expected to be carried out later. An inquest into the four deaths is expected to open next week.
Police are continuing their inquiries in both Shropshire and at the family's home at Milkwall, near Coleford, Gloucestershire.
Mr Jamieson said: "We are continuing to check CCTV cameras for sightings of the vehicle or its four occupants along various routes and we maintain our appeal for any information which might assist the investigation. We are also continuing our efforts to establish Mr Fuller's link with Shropshire and, in particular, with the Pontesbury area."
