On the evening of Friday, November 7, 1969, a 26-year-old nun named Cathy Cesnik steered her green Ford Maverick out of the Carriage House Apartments in southwest Baltimore. She had two errands: cash her paycheck and find an engagement gift for her sister at the Edmondson Village shopping center. She told her roommate she would not be gone long. She never came back. At 4:40 the next morning, two priests found her car sitting muddy and illegally parked around the corner from her own front door. Sister Cathy was nowhere in sight.

A Young Nun Who Chose the Classroom

Catherine Anne Cesnik was born in Pittsburgh on November 17, 1942, the valedictorian of her 1960 high school class, and she entered the School Sisters of Notre Dame at eighteen. The order sent her to Archbishop Keough High School, an all-girls Catholic school in southwest Baltimore that opened in 1965, where she taught English and drama and became one of the most popular teachers in the building. In 1969, in the experimental spirit that followed the Second Vatican Council, she received permission to live outside the convent. She and another young nun, Sister Helen Russell Phillips, took an apartment at Carriage House, and that fall Cesnik began teaching at Western High School, a public school across town.

Two Errands and an Empty Car

Cesnik left the apartment around dinnertime on November 7. She cashed her paycheck and is believed to have stopped at a bakery in Edmondson Village, a few minutes from home. When she had not returned by late evening, her roommate called two priest friends, Gerard Koob and Peter McKeon, who contacted police. Investigators later concluded that someone accosted the young nun in front of her residence as she returned from the store and forced her back into her own car. The Maverick turned up before dawn, close enough that whoever abandoned it could have walked away in minutes. Searches of the surrounding neighborhoods found no trace of her.

Fifty-Seven Days

On January 3, 1970, two hunters walking near a garbage dump off Monumental Avenue in Lansdowne, in southwestern Baltimore County, found a woman’s body lying in the snow. It was Cathy Cesnik. The medical examiner ruled that she died of blunt force trauma to the head. As with the Grimes sisters in Chicago thirteen years earlier, weeks of official searching had ended with a chance discovery in the winter cold. And Cesnik was not the only young woman taken that November. Four days after she vanished, 20-year-old Joyce Malecki disappeared during a shopping trip in the Baltimore suburbs; her body was found two days later on the Fort Meade military base. She had been strangled. Her murder, handled by the FBI because of where she was found, also remains unsolved.

The Secret at Keough

For two decades the case sat cold. Then, in 1992, a former Keough student named Jean Wehner came forward with an account that reframed everything. She said Father A. Joseph Maskell, the school’s chaplain and counselor from 1967 to 1975, had sexually abused her. She said she had confided in Sister Cathy, who asked her gently, “Are the priests hurting you?” and promised to handle it. Wehner also said that after the nun disappeared, Maskell drove her to see the body and warned her about what happens to people who talk. In 1994, Wehner, identified in court papers as Jane Doe, and another former student, Teresa Lancaster, sued Maskell and the archdiocese. The case was dismissed under Maryland’s statute of limitations, with no ruling on the truth of the claims. Maskell was removed from ministry on July 31, 1994, spent years in Ireland, and died of a stroke on May 7, 2001, at age 62. He was never charged with any crime.

The Keepers and the Exhumation

On May 19, 2017, Netflix released The Keepers, a seven-part documentary built around two retired Keough alumnae, Gemma Hoskins and Abbie Schaub, who had spent years gathering records and interviewing classmates about their teacher’s death. The series drew millions of viewers and a wave of new tips. It arrived as Baltimore County police tested an old theory: on February 28, 2017, detectives had exhumed Maskell’s body to obtain a DNA sample. That May, the department announced the result. His DNA did not match the forensic profile developed from the 1970 crime scene, though investigators cautioned that the exclusion did not fully clear him as a suspect. DNA from roughly six suspects has been compared over the years, with no match, and searches of the FBI’s CODIS database have come back empty.

The Reckoning on Paper

What Jean Wehner alleged in 1994 no longer sounds isolated. On April 5, 2023, the Maryland Attorney General released a four-year investigation finding that 156 clergy and other personnel connected to the Archdiocese of Baltimore had abused more than 600 children over eight decades, and that church officials repeatedly covered for them. At least 39 people told investigators that Maskell had abused them or someone they knew, and the archdiocese had already paid $472,000 in settlements to sixteen of his accusers. On September 29, 2023, two days before Maryland’s Child Victims Act erased the civil statute of limitations, the archdiocese filed for Chapter 11 bankruptcy, moving every survivor claim into federal court. A century after the Hall–Mills murders showed how a church scandal could swallow a murder investigation, Baltimore was living its own version.

Where the Case Stands in 2026

The investigation has not stopped. In December 2023, the FBI exhumed Joyce Malecki’s remains from Loudon Park Cemetery in pursuit of DNA evidence in her case. The bankruptcy, meanwhile, grinds on: roughly 1,000 survivors have filed claims, the archdiocese has proposed a settlement of about $250 million, including $100 million pledged by insurer The Hartford in April 2026, while the survivors’ committee has countered at $873 million. Mediation is due to conclude by the end of September 2026, or the court may reconsider dismissing the case entirely. Sister Cathy’s murder remains open with Baltimore County police, who still offer a reward of up to $2,000. Old cases do close. America’s Unknown Child was finally identified in 2022 after 65 years, a reminder that DNA can outwait almost anything.

Why This Case Still Matters

The Cesnik case endures because of what it may represent: a 26-year-old teacher who listened to her students and paid for it. That has never been proven, and it may never be. But the questions her death raised helped force open the records of one of America’s oldest archdioceses, and the people who did the forcing were not detectives. They were her former students, retired teachers and grandmothers who filed records requests, knocked on doors and refused to accept silence. Every survivor claim now moving through the Baltimore bankruptcy traces, in some part, to the road they cleared. The murder is unsolved. The reckoning it started is not finished either.

Whoever killed Sister Cathy drove her car back to Carriage House and left it within sight of her front door, on a street he evidently knew well. Fifty-seven years later, that short drive is still the closest anyone has come to seeing his face.
