The Observer

Introducing...The Lab Detective

Kathleen Folbigg experienced unimaginable loss. All four of her infant children died suddenly, over a 10-year period. Their deaths were unexplained. Until a police detective turned up at her door, and arrested Kathleen on suspicion of murder. 

She was labelled ‘Australia's worst female serial killer’, convicted, and was destined to spend most of the rest of her life in jail. 

Until a different type of detective entered her life. A scientist working in a lab who uncovered the truth behind the deaths. 

This is the story of a shocking miscarriage of justice, but as journalist Rachel Sylvester starts to investigate how this happened, she learns that Kathleen is not alone – other mothers have endured the same fate, and may also be in prison. 

The Lab Detective is a story about the power of science, and the determination of those searching for the truth.

The full series is available to listen now.

You can watch a short documentary on the genomics team behind Kathleen Folbigg's case filmed at the Crick.

Introducing...The Lab Detective

When Lucky Boy launched back in March, there was an important detail that didn't make it into the podcast, for legal reasons: the team had discovered that they weren’t the only people who had been investigating the allegations made by Gareth - the Metropolitan Police had been too. 

Now, reporter Chloe Hadjimatheou has an update.
