What were the miracles attributed to Samuel Charles Mazzuchelli?

In August 2008, an official inquiry into a presumed miracle performed through the intercession of Mazzuchelli was completed in the Diocese of Madison, Wisconin. Robert Uselmann, a resident of Monona, Wisconsin had gone to Sinsinawa Mound with his family in 2001 to pray to Mazzuchelli for his intercession in curing him of cancer. While there he prayed with the sisters, using Mazzuchelli's penance chain. Uselmann later discovered that a cancerous tumor had disappeared from his lung. The Sacred Congregation for the Causes of Saints in the Vatican is investigating the miracle.
