Detectives from the Homicide and Major Crime Command are carrying out an investigation into the death of a family.
Police attended a house in Grove Road, Chadwell Heath, at 13.10hrs on Tuesday, 12 May in response to concerns about the welfare of the residents.
On arrival, officers forced entry and found the bodies of a woman, believed to be aged 37, and two girls, believed to be aged 13.
A forensic and specialist examination is ongoing at the scene.
Detectives had been carrying out urgent enquiries to trace a 45-year-old man, who was missing from the address.
At 08:17hrs today, Wednesday, 13 May, police were called to Woodford Reservoir, Walthamstow to reports of a man found hanging. He was pronounced dead at the scene.
This afternoon detectives are now able to confirm that they are confident that he is the man they were trying to trace.
At this stage, formal identification has not taken place and next of kin have not been informed. However, we believe we know the identity of the deceased and believe their relationship to be mother, father and twin daughters.
Post-mortem examinations will start later today, Wednesday, 13 May. We will not speculate on cause of death, however the female bodies have no signs of visible injuries.
The last confirmed sighting of the family was on Sunday, 10 May.
Detective Superintendent Kenny McDonald, who is overseeing the investigation from the Homicide and Major Crime Command, said:
“At this stage we are awaiting the outcome of the post-mortems to confirm cause of death, which will provide further evidence of what has taken place inside the house at Grove Road.
“However, at this stage in our ongoing investigation we are not looking for anyone else in connection with the deaths.
“We are making extensive enquiries to trace next of kin, who we believe to be outside of the UK.”
Police attended the address in Grove Road late on the evening of Monday, 11 May, but there was no response and no signs of any disturbance. As is routine in these circumstances, the Directorate of Professional Standards is reviewing the police response and a referral to the Independent Police Complaints Commission was made on Tuesday, 12 May.
