Kane surprised all who knew him when in 1989 he joined The Church of Jesus Christ of Latter-day Saints. In 1998 Kane started volunteer work as a librarian assisting the public with genealogy at the Family History Center at the Los Angeles Temple. It was while browsing the Social Security Death Index (SSDI) on microfilm one day in the genealogy library that Kane discovered that his father, with whom Arthur had been estranged since the death of his mother in 1966, was deceased.
