The Sears moved to Tucson in 1985 in part for his health as the climate was better for him. He published "All Flags Flying" to tell anecdotes from his travels. In 1986 he attended the dedication of the Lotus Temple and gave a talk that has been recorded. The Sears' then began a project establishing Desert Rose Baháʼí School which had its first meetings in 1988. Despite having developed prostate cancer, in 1991 Sears initiated his last major project - he began to tour five cities of the United States and then extended the tour to nine more. But Sears died before reaching the eighth goal city, on the morning of March 25, 1992. Along the way he published "Run to Glory!" with anecdotes of his life fictionalized and humorous. He also had notes of works not published that were finished and published - "In Grandfather's Barn" and "The Half-Inch Prophecy". He is buried in East Lawn Palms Cemetery in Tucson, Arizona.
