DALLAS (AP) -

Attorney Ray Hutchison, a former legislator, gubernatorial candidate and the husband of former U.S. Sen. Kay Bailey Hutchison, has died. He was 81.

Michelle McCormick, spokeswoman for the Houston-based law firm of Bracewell & Giuliani, confirmed that Hutchison died Sunday. A family spokeswoman, Lindsey Parham, says he died at a Dallas hospital of heart complications.

The firm said in a statement released Monday that Hutchison for more than 50 years served as counsel to state and local governments on development projects. He was involved in the development of Dallas-Fort Worth International Airport, Dallas Area Rapid Transit and other prominent projects in the state.

Hutchison was a chairman in the 1970s of the Texas Republican Party and ran unsuccessfully in the 1978 GOP primary for governor.
