Lisha Barboza, standing with her father Ben, looks towards a picture of her late mother, nurse Jacintha Saldanha.
The Daily Mail and the Telegraph report that Jacintha Saldanha, 46, a mother of four, was treated in intensive care at a hospital in Mangalore, India, in January, after reportedly falling from a building.
A little over a week earlier, she reportedly attempted to overdose on pills during a family visit to India.
But Saldanha's family told the Times of India she never opened up about her mental-health problems.
Her brother said he visited in her hospital after her January fall.
"Even this incident (in January) was not discussed at home for the knowledge of it would have hurt my ailing mother Carmine," said her brother, Naveen Saldanha. "We told her that Jacintha was admitted to hospital for blood pressure problems."
Saldanha was found dead Dec. 7, hanged from a wardrobe with injuries to her wrist. This was just days after she put the hoax call through to a colleague who disclosed details of the treatment being given to Prince William's wife Kate, who was in hospital suffering from acute morning sickness.
The prank made headlines around the world.
DJs Mel Greig and Michael Christian, whose show has been cancelled, have since issued a tearful apology.
London Police have asked prosecutors whether Greig's and Christian's actions warrant pressing charges.
More than 2,000 mourners turned up to Saldanha's funeral in India last week.
