Shane Waters and Gemma Hoskins sit down together for the first time in over a year for a wide-ranging conversation about the unsolved 1969 murder of Sister Catherine Ann Cesnik in Baltimore, Maryland. Known to millions through the Netflix documentary The Keepers, Gemma has spent more than a decade investigating what happened to Sister Cathy, the young School Sister of Notre Dame who taught English and drama at Archbishop Keough High School. She was found dead two months after her disappearance. This episode is a Q&A, recorded live with questions submitted by listeners through the show's Facebook community.

The Investigation: Timeline Questions and New Doubts

Listeners asked about the timeline of the night Sister Cathy Cesnik disappeared on November 7, 1969. Father Gerard Koob, who was in a relationship with Sister Cathy, claims he called the police at 11:30 PM after arriving at her apartment. The police report says the call came at 1:30 AM, a two-hour gap that remains unexplained. Koob says he and Father Peter McKeon found Cathy's car around 3:30 AM during a walk, but the police report credits McKeon alone with the discovery.

Gemma corrects a long-standing detail from The Keepers: the car was not found directly across the street from Cathy's apartment at Carriage House. It was actually found one court up the street, on Carriage Court, around a curve and out of direct line of sight from Lantern Court. She also confirms that the image of Sister Cathy's car shown in The Keepers was digitally placed into the scene by producer Jessica Hargrave as a visual aid. The steering wheel appears on the wrong side because the original police impound photo was flipped to match the camera angle.

Shane and Gemma discuss the suspicious letter Father Koob claims Cathy wrote to him, a handwritten love letter dated 12:30 AM on the Monday before she disappeared. The letter was found in the morgue notes rather than the detective's case file. Shane points out this means it was likely turned over after Cathy's body was found in January 1970, not when she first went missing. A profiler formerly with Scotland Yard analyzed the letter's content and concluded it was not written by Sister Cathy. Koob did not pass his second polygraph examination.

They also examine a separate letter Cathy wrote to her sister Marilyn, postmarked after the disappearance, which was admitted into evidence with the Baltimore County Police but has since gone missing. Shane raises the question of whether Father Koob could have written the letter to Marilyn as well, noting the parallels to the other letter and the movie ticket alibi.

New Evidence: The Mary Statue at St. Clement's

Gemma shares a story that has not been widely reported. Approximately two years ago, Eva Nelson, a publicly identified survivor of Father Joseph Maskell's abuse, told investigators she remembered watching Maskell bury something in the backyard of the St. Clement's rectory in Lansdowne. Police obtained permission from the current property owner and brought in ground-penetrating sonar equipment. Detective Josh Battaglia, the current investigator on Sister Cathy Cesnik's case, was present at the dig.

After two visits and multiple excavations, they found a broken statue of the Virgin Mary buried beneath a large bush that had once been small when Eva was a child. Eva recognized the statue immediately. A nun at St. Clement's had given it to her for protection, telling her, "Mary will always protect you." Father Maskell found the statue, broke it in front of Eva, and forced her to watch him bury it. The discovery validates Eva's memory of events that took place decades ago.

Historical Context

Sister Catherine Ann Cesnik was a 26-year-old School Sister of Notre Dame who taught English and drama at Archbishop Keough High School in Baltimore. She disappeared on November 7, 1969 after leaving her apartment to run errands. Her body was found on January 3, 1970 in a wooded area in Lansdowne. Her murder has never been solved. Father Joseph Maskell, a Catholic priest and school counselor at Keough, was later accused of sexually abusing dozens of students throughout the 1960s and 1970s. Multiple survivors have said they believe Sister Cathy was killed because she was about to report the abuse. Maskell died in 2001 without facing criminal charges. The case was the subject of the 2017 Netflix documentary series The Keepers.
