William Mannion Jr., a former Catholic priest, is on trial in Baltimore County on 15 felony sex and child abuse charges. Prosecutors allege he repeatedly took a young altar server from class at St. Agnes in Catonsville to a nearby rectory and sexually abused him. Mannion denies the allegations. A separate Maryland court record documents an earlier episode in which Mannion reported allegations against another man; that history is distinct from the case jurors are now considering.
Opening statements began Monday, and the trial was expected to last four days, The Baltimore Banner reported. The Banner said prosecutor Lisa Dever told jurors the alleged abuse continued over several years and included forced oral sex. Defense attorney Christopher Luber disputed the account, arguing that repeated absences from class would likely have been noticed by school staff and that former staff members are expected to testify the abuse did not occur.
The Banner also reported that the defense disputes the timeline. According to its account, the alleged victim first described abuse in first through third grades and later placed it in second through fourth grades; the reported end date also shifted from 1994 to 1995. These disagreements are part of the competing accounts before the court, not findings that resolve the charges.
A separate report, and what it establishes
In 1988, Mannion spoke with Elizabeth Murphy about her allegations against former teacher John Joseph Merzbacher and reported them to Archdiocese of Baltimore officials, according to the Maryland Court of Appeals’ account in its 1997 opinion in the separate Merzbacher case. Merzbacher was convicted in 1995 of multiple child-sex offenses, and the appeals court affirmed the conviction in 1997. That history documents Mannion’s role in reporting allegations about Merzbacher; it is not evidence for or against the allegations now being tried.
The defense has also pointed to the Maryland attorney general’s investigation of abuse in the Archdiocese. The Banner reported that attorney Charles Waechter intends to rely on Mannion’s omission from the report, after the attorney general’s office investigated him. The report’s scope should not be mistaken for a ruling on this prosecution: the office says its investigation began in 2018 and examined both abuse allegations and efforts by church leadership to conceal abuse. It says it included 156 people determined to have been the subject of credible abuse allegations, including non-clerical personnel such as Merzbacher. The report does not determine whether the allegations against Mannion in this case are true.
Safeguards came later
The Archdiocese of Baltimore says it implemented mandatory screening and training for employees and volunteers in 2003, after the period described in the allegations. It also says it joined the VIRTUS training and compliance system in 2017. These are dated institutional measures, not evidence about what happened at St. Agnes or whether the charged conduct occurred. The Archdiocese’s policy page describes its stated protections.
The trial therefore concerns a specific unresolved allegation, while the court opinion and the attorney general’s report provide separate historical and institutional context. Jurors must assess the prosecution’s account and the defense’s challenges on the evidence presented in this case.
