A cadet attending the Air Force Academy who was discovered injured in a dorm building has been declared dead.

The Academy said an investigation would be conducted into the cadet's death.

The U.S. Air Force Academy cadet was found injured on April 2 in a dorm at the military school, located in Colorado Springs, and the El Paso County Coroner pronounced him dead at 3:45 p.m., according to a statement from the Academy.

The school will not release the cadet's name and information until his next of kin have been informed, per Defense Department regulations. The statement added that an investigation is underway.

According to the Colorado Springs Gazette, the unidentified cadet was found injured at 2 p.m. at Sijan Hall. Academy spokesperson John Van Winkle told reporters that he did not know what the cadet's injuries were or where in the building he was found.

Classes for the rest of Thursday evening were cancelled and Van Winkle said the school called for "100 percent accountability" to locate where all the 4,000 cadets where on campus. The incident happened in a part of a campus where cadets live and study and it is closed off to civilians.

On releasing the cadet's information, Van Winkle said: "That would be wrong for the family to find out by CNN versus casualty notification team that is there to support, assist and help."

The Air Force Office of Special Investigations will head the investigation into the death.

"The Academy family is deeply saddened by the death of one of our own. Our heart-felt condolences go out to the family and friends of the cadet. Our Air Force family is grieving this loss, and we are committed to helping the family through this extremely difficult time," Academy Superintendent Lt. Gen. Michelle Johnson said in a statement.

The Academy had recently seen some attacks on students. The Colorado Springs Gazette reported back in January the Academy had banned hiking alone in the trails around the military school's hills. The "buddy system" was enacted after a pair of attacks in the area.
