The mother of the three children apparently killed by their father has spoken of her devastation.
Ruth Fuller, mother of Sam, 12, and his sisters Becka, aged eight, and seven-year-old Charlotte, released a short statement through Gloucestershire Police.
Mrs Fuller said: "I don't have the words to describe how I feel at the moment. All I would ask is that I be left alone to grieve for my family."

The bodies of the three children were discovered on Monday at a beauty spot near Shrewsbury, Shropshire. It is believed they died from knife wounds.
The body of their father Ceri Fuller, 35, was found nearby at the Poles Coppice on Pontesbury Hill. He is thought to have fallen from a cliff.
West Mercia Police have recovered a knife and one line of inquiry detectives are following is that Mr Fuller killed the children before taking his own life.
The force launched a murder investigation but described the deaths as a "tragic family situation" and are not looking for anyone else.
Police investigate the area near where the three children were found
Detective Chief Inspector Neil Jamieson, who is leading the investigation, said: "I can disclose that a weapon has been recovered from the scene.
"Officers involved in the search found a knife in the vicinity of where the bodies were found. It will now be forensically examined.
"One line of inquiry being considered is that the father took the children's lives before taking his own."
Mr Jamieson said the old quarry and surrounding woodland would remain cordoned off as officers continue a detailed search of the area.
Post-mortem examinations will be conducted on Tuesday afternoon by a Home Office pathologist and may not be concluded until Wednesday, the detective confirmed.
Becka and Charlie were pupils at St John's Church of England Primary School in Coleford, which older brother Sam had also attended before moving to secondary school.
Mr Fuller worked as a production superviser at the Lydney-based Glatfelter paper mill, having joined in 2002.
Mr Fuller married his wife Ruth in August 2009 and neighbours said they had lived in the village of Milkwall for a year.
University graduate Mr Fuller and the children had left their home near Coleford, Gloucestershire, last Thursday.
Neighbours said the family "kept themselves to themselves" but spoke of their shock.
Janice Ayres, who lives next door to the Fuller family, said: "Very, very sad, I just cannot say any more.
"I didn't even know her name (mother of the children). I have children of my own and I would just be devastated."
Another neighbour, who did not wish to give their name, added: "They hadn't lived here all that long. They kept themselves to themselves."
