Katie and Albert.

A postmortem examination revealed that Katie Dugan was four months pregnant when her body was found beaten and slashed in an empty field in Wilmington, Delaware, in 1892. A two-year investigation led police to believe that Albert Stout, Katie’s former employer, was her killer and the father of her unborn child.

The case remains unsolved.
