The Ghost Signature That Freed a Killer

The Ghost Signature That Freed a Killer

In 1980s Australia, a handwriting expert's testimony convicted a mother of murdering her infant, until a scrap of fabric proved a dingo had taken the child. This is the story of how confident forensic certainty collapsed under a single physical discovery, and what it did to one family's name.

Forensic experts misidentified industrial car sealant as fetal blood inside the family car.

The prosecution used ultraviolet light to claim a bloodied handprint existed on the infant's jumpsuit.

Public perception of guilt was driven by Lindy Chamberlain's stoic demeanor and lack of tears.

Discovery of a tattered matinee jacket near a dingo lair led to Lindy's prison release.

The official record was finally updated in twenty twelve to confirm a dingo caused the death.

Flawed forensic analysis of blood flow patterns was used to suggest a sharp instrument was involved.
