She had four children, five grandchildren and five great-grandchildren.
Arizona Governor Doug Ducey tweeted condolences and thanked Yazzie for her service.
Saddened to learn of the passing of Sophie Yazzie, a World War II Veteran and member of the Navajo Nation. At the age of 105, Sophie was one of the longest living female WWII veterans. Arizona is forever grateful for her service. Our prayers are with her loved ones. #RIP pic.twitter.com/oxsIVgdowT— Doug Ducey (@dougducey) January 26, 2020
"On behalf of the Navajo people, we offer our thoughts and prayers for the family of the late Sophie Yazzie, a matriarch for her family and a warrior for our Navajo people who served our country with great honor and dignity," Navajo Nation President Jonathan Nez said.
