The Air Force Academy is investigating a death on base following the NHL hockey game Saturday night.

The academy is releasing limited details on the event, stating only that the deceased was a civilian and not affiliated with the AFA in any way. A spokesperson with the academy says the north gate was closed during the investigation late Saturday and remained closed until visitor hours resumed at 9 a.m. Sunday.

The deceased was identified Tuesday as 31-year-old Adam Prewitt, but the academy and the coroner's office are not speaking to how Prewitt died at this time. However, witnesses told our news partners The Gazette that the man fell off a bridge just west of the north gate around 11 p.m. These reports have not been confirmed by officials.

The Avalanche game Saturday night was part of the NHL's Stadium Series. There were more 40,000 people in attendance at the game.
