Hi, I'm Sam Mullins, and I'm a writer and podcaster, and I created the critically acclaimed podcasts, Chameleon Wild Boys and Sea of Lies from

CBC's Uncover. And I want to tell you about my brand new podcast. It's called The Expert Witness.

The small city of Akron, Ohio, was drowning in unsolved murders until one day something happened, and suddenly those cold cases started
