KIRKWOOD, Mo. — A Marianist priest who was removed as president of an all-boys Catholic school in Kirkwood after a pair of sex abuse complaints has died at 81.

The Marianist Province of the United States confirmed on Monday that the Rev. Robert Osborne died Sunday in Cupertino, Calif., at a health care facility for members of the Roman Catholic order. The St. Louis Post-Dispatch first reported Osborne's death. No cause of death was released.

Osborne was ousted as leader of St. John Vianney High School in 2006 after he was accused of sexually abusing students. He denied the accusations, and a criminal investigation by St. Louis County prosecutors ended without criminal charges. A civil lawsuit against the school by one of the alleged victims was dropped after a confidential settlement.
