A mother arrested on suspicion of killing her two young children was last night named by sources as Fiona Donnison.
The 43-year-old was held following the discovery in Mill Close, Heathfield, East Sussex, yesterday morning.
Sussex Police said the woman, believed to be from Surrey but with local connections, visited Heathfield police station to report “an incident”.
Officers then found the bodies of a boy and a girl, both aged under five, after forcing entry into a car in what police described as a “tragic incident”.
The suspect, who has yet to be interviewed, was taken to Eastbourne District General Hospital with “apparent self-harm injuries” to her arms and was in a stable condition in hospital last night.
The car was towed away last night for forensic examination as a police cordon was put in place around a nearby three-storey detached house with a ‘sold’ sign outside.
Speaking outside the house, Chief Superintendent Robin Smith said the children's bodies were found in the back of a silver Nissan. He said he could not say how the children had died but officers were not looking for anyone else in connection with the deaths.
“At about 11am a lady came into Heathfield police station clearly suffering from some distress,” he said.
“As a result of what she said to us, members of my team were sent to a car. Inside that car, tragically and sadly, they found the bodies of two young children — we believe both under the age of five.”
Family members have been informed of the tragedy, he said.
He added: “It's a huge tragedy for all involved, and not only for the family — it has a huge impact on the local community.”
Post-mortem examinations will take place today when the identities of the dead children are expected to be released.
Mill Close resident Ian Paseka said: “It's terrible. This is an upper-middle class residential area with no crime whatsoever. We've never had a burglary.”
