"His life was characterized by a tremendous love and care for those closest to him, as well as generosity and kindness to all he knew, including those who appeared before him on the bench," his obituary reads. "He was happiest when he was providing for others, and did so until his passing."
He and his wife were also active members of The Church of Jesus Christ of Latter-day Saints, serving a mission in Washington, D.C.
"He lived honorably and with integrity in every aspect of his life," his obituary reads. "Paul's passion was for his family, both those who preceded him and those who came after."
Keller is survived by his wife, his two sisters and four children.
