Hundreds of pages of secret church files were released on Wednesday, shedding light on the careers of a dozen religious order priests, brothers and nuns accused of sexually abusing children while working in the Roman Catholic Archdiocese of Los Angeles. The files include one case of a priest who later admitted to having sexual contact with more than 100 boys while serving in several Southern California parishes. The papers, which were released under the terms of a $660 million settlement agreement reached in 2007, are the first glimpse at what religious orders knew about the envoys they posted in schools and parishes around the Los Angeles area. The archdiocese itself released thousands of pages under court order this year concerning its own priests who were accused of sexual abuse, but the full picture of sexual abuse in Los Angeles remained elusive without the religious orders’ records. Several dozen more files are expected to be released by the fall.
