A University of Iowa student has died after being found unresponsive on campus grounds early Wednesday as arctic temperatures gripped the Midwest from a polar vortex that has been linked to at least seven other deaths.

Gerald Belz, 18, was found behind an academic building on the Iowa City campus just before 3 a.m. by campus police, KCRG-TV reported. The pre-med student was rushed to a hospital, where he later died.

Police haven’t released a cause of death, but believed the frigid temperatures played a role, FOX28 Cedar Rapids reported. With wind chill, the temperature at the time police found Belz was negative 51 degrees, according to the National Weather Service.

Foul play isn’t suspected and zero alcohol was found in Belz’s system, police said.

Belz’s father, Michael, described his son to KCRG as “a momma’s boy with a tough exterior.”

While the deadly cold weather system that put much of the Midwest into a historic deep freeze was expected to ease Thursday, temperatures could still tumble to record lows in some places before the region begins to thaw out.

Before the worst of the cold begins to lift, the National Weather Service said Chicago could hit lows early Thursday that break the city's record of minus 27 degrees set on Jan. 20, 1985.
