About
The John McCaffary House does not announce its past. It looks like what it has always been: a modest cream-brick home built in 1842, with simple lines, a low roof, and the restrained symmetry of early Wisconsin settlement architecture. But behind that plain exterior is one of the most consequential crime scenes in state history. On July 23, 1850, John McCaffary murdered his wife Bridget here, drowning her in a cistern behind the house after months of reported domestic turmoil. The violence that unfolded on this property would ripple far beyond its walls, reshaping Wisconsin law within just a few years.
McCaffary’s conviction led to his public execution in 1851, a botched hanging that unfolded in front of thousands and exposed the brutal reality of capital punishment. Reformers seized on that moment, and by 1853, Wisconsin became the first state in the nation to abolish the death penalty. Of all the locations tied to that story, this house remains the most intact, still standing on its original footprint, with the site of the cistern behind it forming a direct, physical link to the crime itself. That continuity is exactly why it was added to the National Register of Historic Places in 1978: not for architectural grandeur, but for its role in a turning point of American legal history.
Today, the house exists in a strange tension between ordinary and infamous. It has been converted into a multi-unit residence, and for decades it sat in decline before preservation efforts recognized its importance. There are no dramatic markers out front, no overt reminders of the violence that once occurred here, only the weight of context. This is not a staged attraction. It’s a lived-in structure that carries one of Wisconsin’s darkest chapters beneath its surface.
John McCaffary’s unmarked burial site lies just a short distance away in Green Ridge Cemetery.
