The contents of a note left by London nurse Jacintha Saldanha may shed light on the circumstances of her well-publicised death.
The 46-year-old mother of two died in London on Friday after being found unconscious at her living quarters near the exclusive King Edward VI Hospital where she worked.
British media outlets reported that Ms Saldanha left a note for her family - husband Benedict Barboza and children Junal, 17, and 14-year-old Lisha.
The contents of the note have not been revealed.
While on duty as a senior nurse last week Ms Saldanha answered a hoax call from Australian radio jocks Mel Greig and Michael Christian, who impersonated the Queen and Prince Charles as they sought information about a patient, the pregnant Duchess of Cambridge.
