Maryland’s top prosecutor accused Catholic Church officials in Baltimore on Wednesday of engaging in a yearslong cover-up of the sexual abuse of 600-plus children, some of whom were “preyed upon by multiple abusers over decades.”

State Attorney General Anthony Brown chronicled the abuse in a 463-page report that named several priests and described what they are alleged to have done.

“Time and again, members of the Church’s hierarchy resolutely refused to acknowledge allegations of child sexual abuse for as long as possible,” according to the report.
