Australian mother jailed for baby deaths should finally be cleared, say scientists

Inquiry will hear new evidence of fatal gene mutation that may be to blame

In 2003 Kathleen Folbigg was convicted of smothering and killing her four young children, Caleb, Patrick, Sarah and Laura. She was given a prison sentence of 40 years and dubbed Australia's worst female serial killer.

Folbigg had to be kept in protective custody to prevent violence from other inmates but has steadfastly maintained her innocence, a claim that has slowly gathered support over the years. Scientists, including several Nobel prize winners, have since argued that a mutant gene was responsible for the children's deaths.
