Three children found dead at a property in New Malden most likely died of suffocation, a court has heard.
Tania Clarence, 42, who is accused of killing her three-year-old twin sons and her four year-old daughter, was remanded to a secure hospital under the mental health act during a bail hearing at the Old Bailey today.
Zoe Johnson QC, prosecuting, told the Old Bailey today: "By way of preliminary statement, Dr (Nathaniel) Carey, the pathologist, has indicated that the provisional cause of death is probably suffocation.
"Whether that was associated with some form of intoxication is yet to be determined."
Further tests were being carried out, Ms Johnson said.
