Detective Chad Gish, a 22-year veteran of the Metro Nashville Police Department, tells the story of his crucial role in solving the tragic case of Tiffany Ferguson, a 22-year-old ICU nurse who was brutally murdered in her Nashville apartment on February 28th, 2017. The truth of this case is that a man with no home, job or cellphone service still produced a vast digital footprint for forensic examiners to explore.
