The Springfield (Mass.) Republican reports today that Bishop Thomas Dupre has resigned from the Roman Catholic Diocese of Springfield after the newspaper asked him about allegations that he molested boys before he became a bishop. The bishop’s office says he quit five years ahead of the mandatory retirement age because of health problems. The news story today suggests there may be other reasons. Another wrinkle: after an inexplicable delay, Bishop Dupre recently laicized Fr. Richard Lavigne, a convicted child molester priest who is also a suspect in the long-unsolved murder of a boy. Something may be about to unravel.
