MINNEAPOLIS (WCCO) – First responders in central Minnesota responded to a traumatic call over the weekend when they had to pronounce one of their own dead after he fell onto a concrete patio in the middle of the night.

The Stearns County Sheriff’s Office said Chad Kraemer, a member of the Cold Spring Fire Department’s rescue squad, died at a home just north of Cold Spring. He fell to his death from a sliding glass door to the concrete patio below, a distance of about 10 feet.

It’s not clear when Kraemer fell, but the 911 call came in around 4:40 a.m., the sheriff’s office said. Family members reported that Kramer went to bed Saturday between 11 p.m. and midnight.

First responders from the fire department worked to treat Kraemer’s wounds, and a helicopter was called to transport him to a hospital. Despite their efforts, Kramer died at the scene.

The sheriff’s office says the sliding glass door that Kraemer fell from was the type that would typically lead out to a deck, although this home had no desk installed.

The glass door had no device to stop it from being used.

On social media, nearby fire departments expressed their condolences.
