Former Fort Worth, Texas councilwoman Cathy Hirt and her husband, Darrell, lost their lives when the taxi they were riding in collided with a truck in Budapest, Hungary earlier this month on Friday, October 2.

Cathy Hirt’s brother and Dallas resident, Karl Csaky, said the Hirts were supposed to be flying back to the United States on Saturday after their two-week vacation in Europe, which included trips to Prague and Vienna before a final stopover in Budapest, where Hirt’s parents had once lived, to visit relatives.

The Hirts were known for their charitable contributions and good work in the Fort Worth community. Cathy was a respected councilwoman who had had two bids for a mayoral position, and Darrell was a well-known kidney doctor in town.

The couple is survived by their three children, Karl Joseph, Alex, and Tina. Hirt’s brother said that preparations are underway for a funeral service that will celebrate their lives and mourn their deaths.
