The sexual abuse scandal in the Catholic Archdiocese of Philadelphia, in Pennsylvania, U.S., is a significant episode in the series of Catholic sex abuse cases in the United States, Ireland and elsewhere. The Philadelphia abuses were substantially revealed through a grand jury investigation in 2005. In early 2011, a new grand jury reported extensive new charges of abusive priests active in the archdiocese. In 2012, a guilty plea by priest Edward Avery and the related trial and conviction of William Lynn and mistrial on charges against James J. Brennan followed from the grand jury's investigations. In 2013, Charles Engelhardt and teacher Bernard Shero were tried, convicted and sentenced to prison. Lynn was the first official to be convicted in the United States of covering up abuses by other priests in his charge and other senior church officials have been extensively criticized for their management of the issue in the archdiocese.
