Further testing will be carried out on the burned body found in the back garden of a Southfields address after initial investigations were inconclusive.
A post-mortem examination carried out by Scotland Yard on last Friday (September 22) could not confirm the cause of death.
Although the victim has not yet been formally identified, she has been named locally as French nanny Sophie Lionnet.
Ouissem Medouni, 40, and Sabrina Kouider, 34, both of Wimbledon Park Road, have already appeared in court charged with Ms Lionnet’s murder.
The two were remanded in custody and will appear at the Old Bailey tomorrow (September 26) after the body was discovered last Wednesday afternoon (September 20).
