Two bodies have been discovered and a murder investigation is underway as police continue to investigate a house fire in Croxden Way, Eastbourne.
They are believed to be those of the two occupants previously unaccounted for – a woman aged 34 and her four-year-old son.
Next of kin of the victims have been informed. Formal identity has yet to take place.
The incident happened around 1am and was reported to police at 1.18am on Tuesday (10 July), and the bodies were discovered in a first floor bedroom about 12pm (midday) on Wednesday (11 July).
A 26-year-old man who was also in the property at the time of the fire was taken to hospital with burns injuries in the early hours of Tuesday (10 July), and remains in an induced coma at this stage.
He was the partner of the woman who lived at the house and whose body is believed to have been discovered; he was not the father of the child whose body is believed to have been discovered.
The cause of the fire is currently being treated as arson and a murder investigation is underway. No arrests have been made.
Police are continuing to appeal for anyone with any information to report it online or call 101, quoting Operation Druffield.
Detective Chief Inspector Mike Ashcroft, of the Surrey and Sussex Major Crime Team, who is leading the investigation, said: “This is a dreadful incident and the worst fears have been realised. Our thoughts are with the victims, their families and the whole community at this time.
“I urge anyone with any information about this or any footage of the fire to contact us.”
