What is this?

On a cold February day in 1931, the lifeless body of notorious mobster John Marcus was found in the basement of an abandoned house just outside Hamilton. His hands and feet tied, a single bullet to the head—it was a killing meant to send a message. But to whom? Marcus wasn’t just another Prohibition-era criminal. He served as an enforcer for the infamous “Bourbon King” George Remus and acted as personal bodyguard to Remus’ wife. In a world fueled by illegal liquor, shifting loyalties, and ruthless ambition, Marcus knew secrets—and made enemies. So what sealed his fate? Was it the revenge of a competitor? Or a hit carried out from within his own ranks? Join Executive Director of the Butler County Historical Society, Brian Smith, for a gripping exploration of this long-unsolved case. Combining local history with the intrigue of true crime, this program will take you inside one of Butler County’s most chilling mysteries—and the questions that still remain unanswered.
