The Iowa high school principal who was shot and wounded while trying to protect his students during a school shooting earlier this month has died from his injuries, according to the school district.

Perry High School Principal Dan Marburger was among seven people injured in the Jan. 4 shooting. One student, 11-year-old sixth grader Ahmir Jolliff, was killed, authorities said.

The suspected shooter – a student at the high school – died of an apparent self-inflicted gunshot wound, authorities said.
