[3][4][5] In 1969, a popular English and drama teacher at Archbishop Keough, Sister Cathy Cesnik, was found murdered in the outskirts of the city of Baltimore.

Her murder was never solved and is the central subject of the 2017 Netflix documentary web series The Keepers.

The documentary cited that over a hundred former students came forward to provide testimony on rape, sexual misconduct, and molestation.

Conducted by consulting firms Ayers Saint Gross, DataStory and Fielding Nair International, the study examined school facilities, enrollment, and projected demographic data and potential areas of growth.

The study identified three schools for closure due to under-enrollment and/or facility condition, including Seton Keough.
