When David O’Boyle decided to head to the UCLA track on the morning of June 28, 2016, he didn’t really have a grand plan; he just knew he had to confront Conrad Mainwaring. He wanted to stop him, but he wasn’t really sure how. So, when O’Boyle showed up, he started recording on his phone, and for 12 uncomfortable minutes, he called out Mainwaring as a child abuser. Then he left, unsure what exactly he had accomplished. What he didn’t know – what he couldn’t have known – was that his confrontation was one in a series of unlikely events that ultimately would bring Mainwaring to justice.
