At centre stage of Sin, Shame and Secrets is the media-frenzied murder charge against Reverend Gerald Robinson. In 1980, on Holy Saturday - the day before Easter - an elderly nun was strangled to death in the chapel of a Catholic hospital in Toledo, Ohio. The killer then wrapped the nun's body in an altar cloth and stabbed her 32 times in the face, neck and torso. Police reports described it as a ceremonial killing. The intense, high-profile police investigation in the months that followed the murder included interviews with more than 600 people, including the slain nun's colleagues in the Sisters of Mercy convent, her relatives, hospital staff, patients, and visitors, and a number of suspects ranging from convicted criminals to Satan worshippers, from co-workers to members of the clergy. No arrests were made. Until now. On April 23 2004, Toledo's cold-case squad arrested a slight, mild-mannered 66-year-old priest, Father Gerald Robinson, and charged him in the 24-year old murder of Sister Margaret Ann Pahl. circumstances of Sister Margaret Ann's death and the arrest of a local priest decades later, but also the myriad factors that caused local law-enforcement and criminal-justice officials to come up empty-handed, despite the exhaustive investigation and, as some assert, the compelling evidence pointing to Father Robinson as a prime suspect.
