The church. A sanctuary for those seeking guidance. And a seat of power for those entrusted to lead their flock. We trust our religious leaders with our secrets and we respect them for their wisdom and communion with the Lord. But sometimes our apparently devout men of the cloth are not what they seem. Tempted by sin, tarnished by power and tainted by corruption, they are driven to murder. Through the testimony of law enforcement officers, prosecutors and parishioners, this series showcases 10 terrifying tales of Clergymen who committed the ultimate sin.
