A member of the Nebraska Army National Guard died Saturday following a medical episode during physical fitness training at the armory in Broken Bow, the guard reported Sunday.

Staff Sgt. Trevor J. Kurtzhals, 29, of Lexington, Nebraska, died at Melham Medical Center, according to Maj. Scott Ingalsbe of the guard.

In a statement released Sunday by the guard, Kurtzhals' family has asked for privacy.

He was an 11-year-veteran of the Nebraska Army National Guard and was a member of the 1075th Transportation Company. Kurtzhals was deployed to Afghanistan in 2010.

The statement did not describe the nature of the training exercise other than to say it was routine. Nor did it provide any other details.

“We are deeply saddened by the passing of Sgt. Kurtzhals and our hearts and prayers go out to his wife, his children, his mother and family during this extremely difficult time,” said Maj. Gen. Daryl Bohac, Nebraska adjutant general. “Sgt. Kurtzhals was a valued member of our organization and his loss is felt by the entire Nebraska National Guard.”

Gov. Pete Ricketts extended his condolences to the family in the statement.

“Our thoughts and prayers are with his family, friends and community as we grieve his sudden passing.”
