Dawud Isa Abusida Dawud Isa Abusida, 56, was a veteran Tucson cabdriver who started his own business, Budget Cabs, just two months ago. He also was a scientist, with a master's degree in food science from the University of Arizona, a fact that surprised many of his co-workers, who said he never mentioned it, though he displayed a keen intelligence. His co-workers and his family were not surprised to learn he died while trying to help a sheriff's deputy. His youngest son, Islam, 24, said his father's actions were consistent with the man he had become. "I'm really proud of him and what he did, even though it did cost him his life," he said. He said his father did "a lot of good things and gave good advice. He always told me to plan as if you're going to live forever but prepare yourself like you're going to die today."
Dawud Abusida was a Palestinian who emigrated from Saudi Arabia to the United States, where he thought the future would be brighter for him, his wife and their four children.
He earned his master's in 1979 and went back to Saudi Arabia. He returned to Tucson in 1987 and his family followed in 1989. He wasn't perfect, his son said, and the family had problems early in their stay here. Abusida and his wife, Seham, divorced, but they reconciled and remarried seven years ago. "My dad turned his life around," Abusida said. Islam Abusida said his father's religion was important to him and the reason he named his youngest son to honor it. Abusida said he and his father had developed a loving relationship in just the past year. "We cleared up our past and started a new friendship." He said his father stopped by his home Sunday. "He said he missed me and just wanted to see me." In addition to his wife and youngest son, Abusida is survived by his brother, Esam, of Tucson; two other sons, Ala, of Franklin, Ohio, and Eisa, of Phoenix; a daughter, Sohare, who lives in Jordan; and four grandchildren.
