"Our beloved Auxiliary Bishop David O'Conell has passed away unexpectedly," he said. "It's a shock and I have no words to express my sadness. As a priest and later a bishop here in Los Angeles for forty-five years, Bishop Dave was a man of deep prayer who had a great love for Our Blessed Mother. He was a peacemaker with a heart for the poor and the immigrant, and he had a passion for building a community where the sanctity and dignity of every human life was honored and protected."
