A heavily pregnant woman who fell to her death before her three young children were found dead was "a beautiful, intelligent girl" who cared too much, her family said.
Fiona Anderson (23) has been formally identified after she suffered fatal head injuries at a multi-storey car park on Monday morning.
Officers investigating the incident later found the children – named by neighbours as Levina (3), Addy (2), and 11-month-old baby Kyden – at their home in Lowestoft, Suffolk.
In a statement, Ms Anderson's family said she "cared passionately" but had suffered with mental illness from a young age.
Post-mortems on all three children had failed to ascertain the cause of death. Further tests are expected to take place.
