Christopher Sher Eney died from a gunshot sustained during a Capitol Police training exercise on August 24, 1984. He was taking part in a Containment and Emergency Response Team drill inside a vacant Capitol Hill building at 128 C Street NE when, near the exercise’s end after officers had trained with blanks and weapons were reloaded, a colleague’s firearm discharged and struck Eney in the lower back. He succumbed to his injuries the same day.

His wife, Vivian Eney Cross, and their two daughters survived him, and his name is etched on the national memorial honoring fallen officers.

Are there details about the exercise, safety procedures, or witnesses from that day that anyone can share?
