Joe Miller, who coached the Liberty girls’ basketball team, died Friday after a “medical emergency” during a basketball camp at Liberty High School.

In a letter from Liberty that was shared to Facebook, it said that the emergency happened at Liberty at the basketball camp, which hosted third through fifth graders as well as grades sixth through eighth for the two-day event.

“Earlier (Friday) during a summer basketball camp at Liberty High School, Coach Miller experienced a medical emergency on site,” the letter read. “Emergency personnel responded, and we are working with the Colorado Springs Fire Department and the Colorado Springs Police Department. Because this type of incident involves an active response and review, details are limited at this time.”

Miller worked in Academy School District 20 for more than 10 years and, in addition to serving as the girls’ basketball coach, was an assistant with the Lancers’ football team.
