Fire børn døde over ni år. En mor idømt 30 års fængsel. Og en frihedsrejse, der vendte australsk retshistorie på hovedet.
Kathleen Folbigg is the Australian woman who spent more than two decades branded as the country's most notorious child killer — and who in 2023 became a symbol of what can go wrong when the justice system collides with the blind spots of science. The case unfolded in New South Wales, Australia, and spans a period from 1989 to 1999, during which Folbigg's four children died under seemingly inexplicable circumstances. What began as a tragedy evolved into one of Australia's most debated criminal cases in modern times.
The four deaths
Between 1989 and 1999, Kathleen Folbigg and her then-husband Craig Folbigg lost all four of their children. Caleb died at 19 days old in 1989. Patrick survived to nearly eight months but suffered seizures and eventually died in 1991. Sarah died at the age of ten months in 1993. The eldest, Laura, had almost reached her second birthday when she died in 1999. The deaths were initially regarded as tragic but natural — cases of sudden infant death syndrome (SIDS) or illness.
Caleb dør som spæd
Kathleen og Craig Folbiggs første barn, Caleb, dør 19 dage gammel. Døden registreres som naturlig.
Patrick dør efter anfald
Det andet barn, Patrick, dør knap otte måneder gammel efter en periode med tilbagevendende anfald.
Laura dør — politiet adviseres
Det fjerde og ældste barn, Laura, dør som toårig. Dødsfaldsmønsteret får myndighederne til at indlede efterforskning.
Kathleen Folbigg arresteres
Efter Craigs fund af dagbøgerne og politiets efterforskning anholdes Kathleen Folbigg og sigtes for drab på sine børn.
Dom: 30 års fængsel
Folbigg kendes skyldig i Newcastle District Court og idømmes 40 år, reduceret til 30 med mulighed for prøveløsladelse efter 25 år.
Genetiske fund offentliggøres
Forskere publicerer resultater om CALM2-genmutation hos Folbigg og to af hendes døtre, hvilket antyder en arvelig hjertesygdom som mulig dødsårsag.
Benådet og løsladt
NSW-guvernør Margaret Beazley benåder Kathleen Folbigg. Hun forlader fængslet efter næsten 20 år.
Alle domfældelser annulleres
Court of Criminal Appeal ophæver samtlige domfældelser officielt og erklærer Kathleen Folbigg for uskyldig i alle anklager.
It was Craig's discovery of Kathleen's private diaries that changed everything. In them, he found passages he interpreted as admissions — fragments about anger, about a loss of control, and about a sense of guilt. He went to the police, and the investigation began.
The 2003 trial
In 2003, Kathleen Folbigg was brought to trial in Newcastle, New South Wales. The prosecution built its case largely on two pillars: the contents of the diaries and the statistical argument that four sudden infant deaths within the same family must by definition be suspicious. The then widely accepted — but since heavily criticised — logic that the probability of four natural SIDS deaths in one family is astronomically low carried considerable weight.
Folbigg was found guilty of the murder of Laura, the manslaughter of Caleb, and the murder of Patrick and Sarah. She was sentenced to 40 years, reduced to 30 with the possibility of parole after 25.
The diaries as evidence
The diaries were the centrepiece of the prosecution's case. Passages such as "sometimes I feel like she's a reflection of me and that scares me" and references to having lost patience with the children were read as cryptic confessions. The defence's argument — that the diaries represented an emotionally burdened woman's attempt to process grief and self-reproach — failed to reach the jury.
