FOLLOW KILLER INSTINCT ON INSTAGRAM! @killerinstinctpodcast Sadie Hartley was a hardworking & successful businesswoman who began dating a man named Ian Johnston. Little did Sadie know that simply by being with Ian, that would cause a ripple effect that would lead to her murder. Savannah explores the tragic backstory of one of Sadie's murderers Sarah Williams, Sarah's torrid affair with Ian, and how Sarah and her accomplice Katrina Walsh planned Sadie's murder for nearly 2 years before brutally attacking and killing her in her own home. Sarah and Katrina are currently serving lengthy sentences in prison, while Ian has been cleared of any involvement, despite several people, including Sadie's family, suspect he is not as innocent as he seems.
