The Vatican's sex crimes investigator has ended his mission in Chile, and Catholic officials say he plans to deliver a report to the Pope on a Chilean bishop who has been accused of ignoring sex abuse by a priest. Archbishop Charles Scicluna closed his visit on Wednesday with a message expressing gratitude for "the welcome of the Chilean people" and also thanking abuse victims for meeting with him. The statement came a day after Scicluna interviewed several victims of sex abuse by members of the Marist Brothers religious order, a development that suggested his mandate had expanded beyond looking into allegations of a cover-up by Osorno Bishop Juan Barros. Victims of paedophile priest Fernando Karadima have said that as a priest Barros witnessed and ignored the abuse. Barros denies that.
