The inquest into the death of 14-year-old Alice Gross has been opened and adjourned today.
The murdered schoolgirl's mother Rosalind Hodgkiss, 50, was at West London Coroner's Court for the brief hearing.
Alice, from Hanwell, in west London, disappeared on August 28. Her body was found on September 30.
The court heard Alice's body was found by London Fire Brigade divers, wrapped and weighted down in the River Brent.
A cause of death was not established by a postmortem examination and further tests are being carried out.
The coroner has adjourned proceedings until January 29, 2015, to allow those tests and the police investigation to progress.
Coroner's officer John Chadwick told the court: "The deceased was found submerged, wrapped in a bag, and had been weighted down.
"Alice was pronounced life extinct at 22.45pm."
Arnis Zalkalns, the prime suspect in the killing, was found hanged in a west London park on 4 October.
The 41-year-old Latvian builder had served seven years in prison in his native country for bludgeoning and stabbing his wife Rudite to death before moving to the UK in 2007.
