A community college student died suddenly at Jack Trice Stadium Saturday during the Iowa State/Colorado football game.

Heather Heemsbergen, 19, of rural Bloomfield, suffered a pulmonary embolism and collapsed while walking down the steps of section 12, in the southwest part of the stadium.

She was taken to Mary Greeley Medical Center, where she was pronounced dead.

John Tinker, investigator of the Department of Public Safety, said Heemsbergen collapsed at 11:10 a.m., and paramedics arrived on the scene immediately.

“They were there within a very short period of time,” he said.

Dr. Mark Blaedel, a staff physician at the ISU Student Health Center, said a pulmonary embolism occurs when a blood clot is “released from someplace in your body and ends in your lungs.”

Heemsbergen was a student at Southeastern Community College in Burlington. She was attending the football game with her family.
