The Mark

In 1994, wealthy Newport Beach businessman Bill McLaughlin is shot and killed in his own kitchen. His girlfriend Nanette Johnston and her secret boyfriend, ex-NFL player Eric Naposki, are immediately suspicious…but the stories don't hold and prosecutors can't make charges stick. The case goes cold, leaving Bill's family without justice for over a decade. Fifteen years later, Orange County DA Matt Murphy picks it up, determined to finally prove what really happened and who arranged it.
