Police investigating the death of an entire family across two separate locations have revealed that the woman died from stabbing, while her husband and sons fell from height.
Officers gave an update after police found the bodies in near-simultaneous discoveries in Twickenham and East Sussex on March 5.
Following a post-mortem at Kingston Mortuary, the cause of death of the 47-year-old woman found in Twickenham was given as multiple stab wounds.
Examinations at the same facility found that the women's 57-year-old husband and their sons, aged seven and 10, died from injuries consistent with a fall from height. Their bodies were found at Birling Gap seafront, less than a hour before the mother's body was found in south-west London.
Officers from the Met's Homicide and Major Crime Command are continuing the investigation, supported by colleagues in Sussex Police.
Next of kin have been informed. No arrests have been made, and enquiries continue.
At this stage, police are not looking for anyone else in connection with this investigation.
Anyone with information is asked to call the Metropolitan Police on 0208 721 4005, or locally to Sussex Police on 101 quoting Operation Glasson.
