Police continue to investigate the deaths of two people at a residential address in Rainham.
Although formal identification is yet to take police, officers are satisfied that the deceased are Simbiso Aretha Moula, 39, (12.3.79) and her husband Garikayi Moula, 51, (26.6.67) of Rainham.
Post mortem examinations took place at Queens Hospital Mortuary in Romford on Sunday, 6 January. Provisional cause of deaths were confirmed as:
Simbiso Aretha Moula - compression of the neck; Garikayi Moula - suspension.
Officers were called to the couple's home in Lower Mardyke Avenue, Rainham by London Ambulance Service (LAS) at 07:50hrs on Friday, 4 January, after Mr and Mrs Moula were found deceased.
Next of kin have been informed and are being supported by officers. Following the post mortem examinations Simbiso's death is being treated as murder; Garikayi Moula's death is not being treated as suspicious.
Nobody else is sought in connection with their deaths.
Detectives from the Met's Homicide and Major Crime Command are investigating.
Detective Chief Inspector Paul Considine said: "I would like to thank those members of the public with whom we have spoken as part of our inquiry thus far.
"We are ensuring that next of kin are being fully supported at this most difficult of times.
"If you heard or saw anything at the address that seemed out of place or of concern between the hours of 10.30pm on Thursday, 3 January, and 8.00am the following day, please don't hesitate to contact us."
