Most Australians thought the dingo was a flimsy excuse. Few people, except park rangers, believed a dingo would attack a baby, and the evidence indigenous trackers gave about drag marks near the tent was brushed aside. In a 1984 poll, 76.8 percent of Australians said Lindy Chamberlain was guilty, and the investigation did little to change their minds.

Then there was Lindy Chamberlain herself. She was thought too “sexy” and “cold”; she walked into court with a face set like concrete under large black sunglasses and severely cut black hair. Much was made of her bare, tanned shoulders, her expansive wardrobe and her stoicism. When she did not weep on cue, no one suggested she might have been suffering from shock or trauma. Even worse, she was accused of playing to the cameras that were constantly thrust in her face. She was, we were told, more interested in looking pretty than in the death of her child.

This was a woman, as the prosecution put it, who could murder a baby with nail scissors in the front seat of her car before stuffing the body into a camera case. When a forensic expert claimed there were bloodstains in the front of the Chamberlain’s car, those harboring suspicions were triumphant. Guilty! People spat on her as she walked into the courtroom. It took years before it emerged that the marks were from a chemical spray and old milk.

When “A Cry in the Dark” was released in 1988, it presented a significant challenge to public opinion, coming as it did on the heels of a commission that established serious bungling of evidence by the police and judiciary and overturned the conviction for which Lindy Chamberlain served three years. The movie offered a sympathetic portrayal of a woman struck by an inexplicable tragedy and then accused of an inexplicable crime. By then, she had already given birth in prison to her fourth child, who lived with foster parents until her mother was released. Many people wrote her apologetic letters after seeing the film.

When the coroner tearfully declared the Chamberlains innocent this week and gave them Azaria’s correct death certificate, there was a surprising display of grief and shame in Australia. Comedians issued public apologies for using Lindy Chamberlain as a punch line; TV hosts were grave and emotional. Azaria would have turned 32 on June 11; her parents’ faces crumpled when reminded of it.
