A post mortem suggests that 11-year-old Evha Jannath died from chest injuries, following an incident at Drayton Manor theme park.
The Leicester schoolgirl died at Birmingham Children's Hospital after falling from the Splash Canyon ride last week.
Police say the preliminary cause of death has been identified by the HM Coroner as chest injuries, however investigations continue.
An inquest has been opened and adjourned this afternoon (17 May), with no confirmed date for the full hearing.
A joint investigation into Evha’s death is being carried out by Staffordshire Police and the Health and Safety Executive.
