Potential link to murder of Catherine Cesnik In 1994, two former
Archbishop Keough High School students who had suffered alleged
sexual abuse at the hands of Father
Joseph Maskell filed a lawsuit against the
Archdiocese of Baltimore. Maskell had been the priest of St. Clement Roman Catholic Church—where the Malecki family had worshipped—between 1966 and 1968; he also worked as a counselor and
chaplain at Archbishop Keough High School between 1967 and 1975 in addition to serving as a
military chaplain at Fort Meade. One of the staff members at Archbishop Keough High School was 26-year-old Sister Catherine Cesnik, who is strongly believed to have discovered Maskell and other staff members—including Father Edward Neil Magnus—had been sexually abusing pupils shortly before her November 7, 1969 murder. Cesnik's body was discovered in a remote area of Lansdowne on January 3, 1970. The cause of death was determined to be extensive
blunt force trauma to the skull. Malecki had known Maskell via her church and had harbored a strong dislike for him—even informing her family and friends they should "stay away" from him. However, although she is known to have once attended a week-long
religious retreat in which Maskell had served as a spiritual advisor, He and Magnus are believed to have sexually abused a minimum of thirty-nine minors—the vast majority, though not all, female—throughout the 1960s and 1970s. On February 28, 2017, Maskell's body was
exhumed in order to undergo
DNA testing for comparison against a
DNA profile developed from evidence recovered at the scene of Cesnik's murder. Although Maskell's DNA did not match the original 1970
forensic profile, this development does not definitively discount him as a suspect in Cesnik's murder.
Other homicides The murders of Malecki and Cesnik have been speculated to be linked to four further murders committed within the Baltimore region between 1970 and 1981. All four of these murder victims were teenagers, three of whom had alleged connections to Maskell and Magnus and/or two Catholic Baltimore-area parishes where Maskell had served or lived during the years the murders had occurred. Her body was discovered less than a week later in
Anne Arundel County, placed between the eastbound and westbound lanes of what was then Maryland Route 177 (now
Maryland Route 100). On September 27, 1971, a 16-year-old
Franklin High School cheerleader named Grace Elizabeth Montanye disappeared from a shopping center in
Reisterstown. Her bludgeoned body was found discarded behind a Catholic Church close to
Mount Auburn Cemetery in South Baltimore two days later. Francis Daniel Crocetti, a 14-year-old
altar boy, was stabbed to death with an ice pick on the evening of March 24, 1975; his body was discovered in woodland behind the Our Lady of Victory Church in
Catonsville. At the time of Crocetti's death, Maskell had served within and resided at the
rectory of this church. Six years later, in September 1981, a 14-year-old parishioner of the Our Lady of Victory Church, Heather Ann Porter, was abducted in
Halethorpe; her strangled body was discovered in nearby woodland the following day. Via
DNA profiling, Porter's murderer was identified as John Anthony Petrecca, Jr. in September 2021. Petrecca—a convicted rapist—had lived in Halethorpe and was 38 years old at the time of Porter's murder; he had died of natural causes at the age of 56 in January 2000. In March 2023, investigators announced they had identified the perpetrator of Pamela Lynn Conyers' murder as Forrest Clyde Williams III. This identification was facilitated via the use of
genetic testing and
forensic genealogy. Williams—21 years old at the time of Conyers' murder—had died of natural causes at the age of 69 in March 2018. ==Ongoing investigation==
