In 2015 a Florida courtroom heard how Rebecca Fenton ruthlessly gunned down her husband in their home, before ransacking the house to make the crime look like a burglary gone wrong. It had taken police six years to find enough evidence to charge Fenton and in this eerily captivating interview with Piers Morgan, she maintains her innocence from her prison cell.

As Piers recounts the case, an avalanche of evidence against Fenton accumulates and he struggles to find anyone who agrees with her – even her own mother. Yet he can’t quite penetrate Fenton’s steely bravado and struggles in his bid to uncover the truth of what really happened on that fateful day.
