History isn't always written in the halls of government or on the battlefields of revolution. Sometimes, it's tucked into the rugged edges of Pennsylvania’s landscapes — like the Welsh Mountains of Lancaster County, where the Buzzard Gang built their legend.

On a recent episode of The Spark, I sat down with historian and criminal justice expert Michael Zimmerman to explore the dark and fascinating legacy of this infamous local family of outlaws. Zimmerman, who grew up on the edge of the Welsh Mountains himself, has spent decades researching the Buzzards — a group of six brothers and their extended gang who terrorized southeastern Pennsylvania from the late 1800s through the mid-1900s.
