A wildfire killed their loved ones in Spain. These British families demand to know why

The fragments were eventually sent to Madrid for testing. The family says police have now told them no DNA was recovered and that the bones were those of an animal.

But Gillam-Kirton says experts, including a forensic anthropologist who worked on the Grenfell Tower fire investigation, believe the fragments were human.

"We still don't know who or what they are," she said.

Gillam-Kirton complained to the Guardia Civil. She says the reply told her only that the matter had been passed to the courts, and offered condolences for "the death of your relative", in the singular, when in fact she had lost both her parents.
