A 25-year-old man that suffered serious injuries earlier this week after falling around 30 feet remains hospitalized in critical condition. The accident occurred at just before 9:30am Monday at a farm site 4 miles south of Olivia in Renville County. Steven Flannigan of Cold Spring had apparently been working on top of a newly constructed building when he fell through an open section of roof to the concrete 30 feet below. He was flown to Avera-McKennan Hospital in Sioux Falls, where he remains in critical condition. The Renville County Sheriff’s Office is investigating the incident.
