Billing Aquadrome lake girl death: More tests needed
Further tests will be carried out on a toddler's body which was pulled from a lake after initial tests failed to determine a cause of death.
Mandi Munhuwa, two, from Northampton, had been missing for a short time before she was discovered in water at Billing Aquadrome on 10 March.
She died last week after being treated in hospital.
The inquest into her death was opened and adjourned by Northampton Coroner Anne Pember on Wednesday.
