a week after the priest was arrested on child pornography charges. Independent investigation On June 9, 2011, Finn appointed former U.S. Attorney Todd P. Graves to conduct an independent investigation of diocesan policies and procedures used to address sexual misconduct by church personnel, including Ratigan. Graves was the national co-chairman of the U.S. Justice Department's Child Exploitation Working Group. Finn also announced the appointment of an independent public liaison and ombudsman. In the report issued in September 2011, Graves said the key finding of the investigation was "that Diocesan leaders failed to follow their own policies and procedures for responding to reports" of sexual abuse by clergy. Conviction Investigation showed that the diocese waited five months to inform police that Ratigan's computer held inappropriate images of children from diocesan school . During that time, the diocese did not inform the community and Ratigan proceeded to take more inappropriate pictures of children he met through church contacts. The indictment charged Finn with failing to inform police about child pornography. According to the indictment, the diocese was made aware of those images on December 16, 2010. Rather than reporting it, Finn ordered Ratigan to undergo psychiatric evaluation, then sent him to a convent under orders to have no contact with children. Without Finn's approval, other diocesan officials reported Ratigan's actions to police on May 11, 2011. Ratigan eventually pleaded guilty to five counts of producing child pornography and was sentenced to 50 years in federal prison. On October 14, 2011, a county grand jury indicted both the diocese and Finn personally for failure to report suspected child abuse, a criminal misdemeanor. While other bishops had been charged with directly perpetrating abuse, Finn was the first U.S. bishop to be charged in his role as a supervisor of priests, the first criminal case against a sitting bishop in the child sex abuse scandal in the Catholic Church. Finn was convicted on one charge in September 2012 and sentenced to two years of probation. All charges against the diocese itself were dropped. Investigation by Vatican and resignation In September 2014, the Vatican initiated an investigation into Finn's tenure as bishop, conducted by Archbishop Terrence Prendergast at the request of Pope Francis. The director of SNAP called the investigation "overdue". Cardinal Sean O'Malley, the leader of a church commission on child abuse cases, criticized Finn's actions in an interview with the television news program 60
