MADISON, Wis. — David Villa, executive director of the State of Wisconsin Investment Board, has died at age 66, the agency announced.

Villa died Saturday, and his cause of death was not immediately released. Investment board spokeswoman Vicki Hearing told The Associated Press that the board was notified of Villa's death by his wife.

Villa joined the investment board in 2006 as chief investment officer and was named executive director in 2018. A statement from the investment board said Villa was respected as a mentor and visionary, and was globally recognized as a leader in the asset management industry.

The investment board manages the Wisconsin Retirement System, one of the only fully funded public pensions in the country, on behalf of 652,000 current and former employees of state agencies, the university system, school districts and most local governments.

Gov. Tony Evers said in a statement that Villa provided "visionary leadership and the strategic direction to forge a stronger and more certain future for thousands of Wisconsin retirees."
