A woman who was found dead after a fire at her home in North London is thought to have been killed by her husband before the blaze, police have said.
The bodies, believed to be Chloe Siokos, 80 and her husband Argyrios Siokos, 69, were found after a fire at their home in North Finchley on 22 January.
Police have said inquiries reveal injuries on the body of the 80-year-old are "inconsistent" with the suggestion that the fire was the cause of her death.
Metropolitan Police have said they are now treating the incident as a murder, but are not looking for anyone else in connection with the incident.
Fire crews were called to the address at around 06:00am on 22 January to put out the blaze. Emergency services found the body of the woman in the kitchen and the man's body upstairs in the bedroom.
The man is believed to have died as a direct result of the fire. Tests have also indicated petrol may have been poured over the house before the fire started.
The couple, both of Greek origin, are believed to have been separated and had divided the house where they lived into two flats.
A post-mortem examination is due to take place in the next few days.
A Metropolitan Police spokesman said: "Detectives continue to investigate the deaths of a man and a woman whose bodies were found at the scene of a house fire in Finchley.
"Officers from the Homicide and Serious Crime Command are treating the incident as murder. Nobody else is sought in connection with the incident.
"Enquiries have revealed that Mrs Siokos has injuries inconsistent with fire being the cause of death."
Police confirm next of kin have been informed.
