A Tarrant County man claims in a lawsuit filed Tuesday that he was sexually abused as a minor by a priest who taught religion at Nolan High School and served as an assistant pastor at All Saints Catholic Church in Fort Worth. In the lawsuit, a John Doe says that from about 1982 to 1987, when he was a minor, he was sexually abused by Father William Paiz of the Claretian Order in the rectories of All Saints Catholic Church, St. George Church and other places. The lawsuit also alleges that the Fort Worth Catholic Diocese conspired with others to conceal Paiz's abuse of minors. The plaintiff's attorney is Tahira Kham Merritt of Dallas, who has handled a number of such lawsuits. The suit was filed in state district court in Tarrant County.
