John Delaney, 50, of Philadelphia, a clergy abuse survivor and vocal victim advocate, died Friday, Aug. 26, of a drug overdose.

Mr. Delaney fought hard as a victim advocate after coming out publicly in 2005 about his own sexual abuse as a child. Mr. Delaney said he was raped and sexually abused as an altar boy at St. Cecilia’s Roman Catholic Church by the Rev. James Bryzski, who was later called “one of the archdiocese’s most brutal abusers” in a Philadelphia grand jury report. Bryzski, the report said, may have abused more than 100 boys during his time as a priest.
