Though she hailed from Nebraska, Leora Lee Sells was a wholehearted Sooner. She and her husband, Roy Sells, went to almost every University of Oklahoma home game in almost every sport. They had only missed five football games during their marriage. Sells, 58, had sung in the choir at Our Savior Lutheran Church for more than 30 years. She also was a Sunday school teacher and at one time had been a youth counselor for her church. “She was central to the congregation,” said the Rev. Peter Tremain, pastor. Sells, a legal secretary for Housing and Urban Development, also was known for her friendliness when answering the telephone.
