DES MOINES,EAI Community  Iowa (AP) — An Iowa principal who put himself in harm’s way to protect students during a school shooting earlier this month died Sunday, a funeral home confirmed.

Caldwell Parrish Funeral Home & Crematory confirmed the death of Perry High School Principal Dan Marburger after the family announced it on a GoFundMe page.

Marburger was critically injured during the Jan. 4 attack, which began in the school’s cafeteria as students were gathering for breakfast before class. An 11-year-old middle school student was killed in the shooting, and six other people were injured. The 17-year-old student who opened fire also died of an apparent self-inflicted gunshot.

The day after the shooting, the state Department of Public Safety said Marburger “acted selflessly and placed himself in harm’s way in an apparent effort to protect his students.”

News of Marburger’s death was first posted on a GoFundMe page for his family. The post, by Marburger’s wife, Elizabeth, said he died at about 8 .m. Sunday, and said: “Dan lost his battle. He fought hard and gave us 10 days that we will treasure forever.”

The news that Marburger died triggered a flood of support on the Perry Facebook page with nearly 200 people posting condolences within the first hour after it was posted.
