Raúl Héctor Castro died in his sleep today at the age of 98. Castro served as the state's governor from January 6, 1975 – October 20, 1977. He is the only Latino to date to hold the position 

Gov. Doug Ducey issued this statement when announcing the news:

Arizonans will never forget Governor Castro. He was an honorable public servant, a history-maker, a beloved family man and a strong friend and fighter for Arizona. Whether as a county attorney, a superior court judge, a United States ambassador or - as we will best remember him - our 14th governor, his life and legacy of service is forever ingrained in our history. The thoughts and prayers of all Arizonans are with Governor Castro's family and loved ones during this difficult time.

A sad day for Arizona, indeed.
