   97: The Keepers, Where Are They Now

   Shane Waters and Gemma Hoskins close out their reunion by going down the list of the people who appeared in the Netflix documentary The Keepers, where they are today, who is still fighting, who has found peace, and who the world has lost. It is a warm, reflective conversation about the unsolved 1969 murder of Sister Catherine Ann Cesnik, the young School Sister of Notre Dame who taught English and drama at Archbishop Keough High School in Baltimore, and about the community of survivors, investigators, journalists, and filmmakers her case brought together. The Investigators and Advocates Gemma gives an honest update on her own life, recovering from a broken hip, stepping back from the day-to-day advocacy, and finding peace in a quiet home in the woods. She talks about her fellow amateur investigator Abbie Schaub, who remains active in the legislative fight and helps run the official Keepers community online. The Survivors Shane and Gemma share where the survivors are now. Jean Hargadon Wehner, known as "Jane Doe" in the case, is doing meaningful work and published her memoir, Walking with Aletheia. Teresa Lancaster, "Jane Roe, " became an attorney and a leading public voice for survivors, helped pass Maryland's 2023 Child Victims Act, and wrote her memoir, Safe in Socks. Donna testified in Annapolis for the Child Victims Act and helped get Father Neil Magnus added to a public list of credibly accused clergy. They also remember Charles Franz and several of Sister Cathy's former students, including Kathy Hoback, the student Sister Cathy once shielded from Father Maskell, who passed away thispast year. The Journalists and Experts They remember journalist Bob Erlandson of the Baltimore Sun, who covered the case as it happened and died this past year at 94, and renowned forensic pathologist Dr. Werner Spitz, who died in 2024 at 97. Shane and Gemma also revisit Delegate C.T. Wilson, the abuse survivor who championed the Child Victims Act, and journalist Tom Nugent, whose reporting first brought the case back into the light. The Filmmakers Gemma catches listeners up on the team behind The Keepers, director Ryan White, producer Jessica Hargrave, and cinematographer John Benham, whose work since the series includes the Oscar-nominated, Peabody-winning documentary Come See Me in the Good Light. And, of course, they give a nod to Kim, who edits this very podcast. What Comes Next Shane and Gemma agree to keep going as the story unfolds, and invite listeners to suggest the people they would still like to hear from.

   96: The Suspects and the Silence

   Shane Waters and Gemma Hoskins continue their first sit-down in over a year, working through the second half of the questions listeners submitted through the show's Facebook community. This is the follow-up to "The Mary Statue and Unanswered Questions, " 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. The Persons of Interest Listeners asked about the figures who have circled this case for years. Gemma explains why "Brother Bob" has never been publicly identified, how the nickname came to stand for more than one man, and why she has stepped back from the theory she put forward in her own 2019 book. She and Shane talk through how a single murder sits at the center of a web of other abuse and other suspected crimes, and why that makes Sister Cathy's case so difficult to untangle. New Questions Around Father Koob Gemma describes the women who have come forward in recent years with accusations against Father Gerard Koob, and walks through why, in her understanding, charges have been so hard to bring, including questions of jurisdiction and corroboration, since only some of the accusers were abused in Maryland. She recounts asking Detective Josh Battaglia to put her questions to Koob directly. Koob, who was the subject of a 2023 Baltimore Banner investigation by reporter Justin Fenton, continues to deny wrongdoing and says listeners are thinking of a different man. He has not been charged. Who Knew, and the Attorney General's Report Shane and Gemma discuss how much the staff at Archbishop Keough may have known, and why so many people went quiet after Sister Cathy was killed. They place it in the context of the Maryland Attorney General's 2023 report on clergy abuse in the Archdiocese of Baltimore, a 456-page document detailing the abuse of more than 600 children across decades and the conclusion that "no parish went untouched. " That history is part of what is driving the Archdiocese's current bankruptcy. Joyce Malecki and the Sealed Files The conversation turns to Joyce Malecki, the 20-year-old whose 1969 murder near Fort Meade has long been discussed alongside Sister Cathy's. Gemma updates listeners on the 2023 exhumation of Joyce's body, the family's still-unanswered request for thousands of pages of FBI files first sought in 2014, and the letter Senator Chris Van Hollen carried to the White House on their behalf. Shane makes the case for why physical evidence in an unsolved murder should never be destroyed. Cathy's Family Gemma reflects on why Sister Cathy's family chose to step out of the spotlight after The Keepers, the heartbreak of learning their loved one's death may not have been random, and the dignity of their decision to protect their own peace.

   95: The Mary Statue and Unanswered Questions

   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. Content Warning This episode discusses clergy abuse and violence. Frequently Asked Questions Who is Gemma Hoskins?
