Team Of 90 Experts Call For 'Australia's Worst Female Serial Killer' To Be Set Free

Kathleen Folbigg was sentenced to 30 years behind bars in 2003 for killing her four children.

Caleb, Patrick, Sarah and Laura Folbigg died suddenly in their sleep over a 10-year period from 1989 to 1999 and their mum was prime suspect number one because there was no other explanation for their death.

She was convicted of murder in three of the cases and manslaughter in the fourth.

However, a team of 90 expert scientists and doctors have come together to plead for Folbigg's innocence and demand she be released.

They have signed a petition and sent it to NSW Governor Margaret Beazley, arguing that the 'miscarriage of justice' cannot be allowed to carry on any longer.

The group said in a statement: "Not to do so is to continue to deny Ms Folbigg basic human rights.

"Ms Folbigg's case establishes a dangerous precedent as it means that cogent medical and scientific evidence can simply be ignored in preference to subjective interpretations of circumstantial evidence."

In the group lies a few Nobel Prize winners and even a former Australian of the Year.

The team argues the children died as a result of rare genetic traits that were inherited from their parents.

The four children had pre-existing conditions like seizures, breathing difficulties and respiratory infections.

Sarah and Laura Folbigg's had a genetic mutation from their mother known as CALM2, which can cause sudden cardiac death.

Solicitor Rhanee Rego said in a statement: "It's one of the best-recognised causes of sudden death, both awake and asleep, in infants and adults.

"If it's triggered by things like intercurrent infections or drugs like pseudoephedrine, this can actually trigger a cardiac arrhythmia.

"This is what the group of scientists have now found as the likely explanation of Sarah and Laura Folbigg's death."

One entry said: "I feel like the worst mother on this earth. Scared that she'll leave me now like Sarah did. I knew I was short-tempered and cruel sometimes to her, and she left. With a bit of help."

But the team trying to get her out of jail are hoping this new genetic evidence will be able to give more weight to the idea the children died in tragic circumstances due to their genetics.

It's now up to the NSW Governor to decide whether to pardon Folbigg, which will also require her to seek leave to appeal her conviction in the NSW courts.

An inquiry in 2019 upheld the convictions, with Justice Reginald Blanch saying he did not have 'any reasonable doubt' as to Folbigg's guilt.
