The Catholic Church is investigating whether a miracle occurred when a World War II veteran's cancer disappeared in 1997 after he invoked the name of the priest Engelmar Unzeitig, who died in a Nazi concentration camp. If confirmed by the Vatican, the miracle would be the first of three the church requires to declare sainthood for the man, who died of typhoid in 1945. The healed man, a member of the US diocese of Harrisburg, had apparently helped in the liberation of the Dachau concentration camp in Germany. After being diagnosed with cancer, the man mentioned Unzeitig's name in prayers for healing, having heard stories about his heroism in helping to care for fellow prisoners sick with typhoid. The man originally underwent surgery for colorectal cancer in 1995, but doctors told him then that it was impossible to remove all the cancer. He was told that neither radiation nor chemotherapy would be effective treatment. But two years later the man's oncologist told him there was no cancer to be found. The Vatican has already examined Unzeitig's life and declared him a "servant of God," the first step toward sainthood. With two miracles, he would become beatified; and with three achieve sainthood.
