PIERRE, S.D. (AP) — Gov. Dennis Daugaard has requested that all flags in the state be flown at half-staff on Thursday in honor of Presho's late fire chief.

Fifty-four-year-old Donald Manger died after suffering a medical condition while fighting a fire in rural Lyman County on Saturday night. He had served as chief for 23 years, and had 36 years of experience as a firefighter.

Manger's funeral is 11 a.m. Thursday at the Lyman Gardens in Presho. Daugaard asks that flags be flown at half-staff that day from 8 a.m. until sunset.

Manger is the 44th firefighter killed in South Dakota since 1924. He's the 45th South Dakota firefighter to die in the line of duty. David Ruhl of Rapid City died in July 2015 while helping battle a forest fire in California.
