SIOUX FALLS, S.D. (KELO) — South Dakota State Representative Bob Glanzer of Huron has died. He was 75.

Bob had been in critical condition with COVID-19 in Avera’s intensive-care unit in Sioux Falls.

KELOLAND News first learned of Glanzer’s diagnosis on March 23. According to his son, Bob had not traveled abroad. Bob Glanzer represented Beadle and Kingburg Counties.

Bob’s son Tom Glanzer confirmed his father’s passing to KELOLAND News. His son wrote on Facebook, “tonight at 7:57 p.m. our dad, grandpa, uncle, husband and friend went to heaven.” Majority Leader Lee Qualm called him a “true statesman.”

Bob Glanzer is survived by his wife Penny, his children Sally and Tom, and five grandchildren. Tom Glanzer tells KELOLAND News that Penny, who was also diagnosed with COVID-19, is “doing amazing” and has been cleared of quarantine by the South Dakota Department of Health.

His father was not surrounded by loved ones when he passed away, Tom says. COVID-19 is highly contagious.
