By Christine Rousselle, CNA - Bishop Paul Sirba of the Diocese of Duluth, Minnesota died on Sunday, after suffering a heart attack before offering Mass. He was 59 years old… “It is with an incredibly heavy heart that I must inform you of tragic news regarding our Bishop,” said a Dec. 1 statement from Father James B. Bissonette, who had been the diocesan vicar general until the bishop's death. The office of the vicar general ceases upon the death of the diocesan bishop… “Words do not adequately express our sorrow at this sudden loss of our Shepherd,” Bissonette said.
