The woman dubbed by some reports as Australia’s worst female serial killer may have her convictions overturned.

Kathleen Folbigg was found guilty in 2003 for the murders of three of her children and the manslaughter of a fourth child.

Originally jailed for 40 years,  on appeal, her sentence was reduced to 30 years with a non-parole period of 25 years.

Alan Jones was invited by the Salvation Army to see Kathleen in jail.

“I have visited Kathleen Folbigg in jail… to give some hope where it appeared everything was hopeless,” says Alan.

In 2015, lawyers for Ms Folbigg lodged a petition casting doubt on some of the evidence that led to her conviction.

“There was never any evidence whatsoever,” says Isabel Reed, one of the barristers who put the case together.

“It is our view that there is a reasonable doubt into these convictions.

“The irony in all of this is Kathleen was the most fastidious and caring mother. She insisted that anyone who babysat Laura had to have training in CPR. That doesn’t speak of somebody who is then going to go about and smother their child.”

Three years since the petition was submitted, it has now been announced the NSW government will launch an inquiry into Ms Folbigg’s convictions.

Former District Court chief judge Reginal Blanch will conduct the inquiry.
