  • Two people reported hearing at least one gunshot coming from the NASIC building around 9:25 p.m. Thursday

Authorities said two people reported to security that they heard at least one gunshot coming from the National Air and Space Intelligence Center (NASIC) facility at the base around 9:25 p.m. Thursday night. 

An alert was then sent to all base personnel to seek cover away from the threat because of a possible active shooter. Officials investigated the 850,000 square-foot, three-story building for four hours before giving the all clear.

Col. Patrick Miller, the Installation Commander at Wright-Patterson AFB, said no threat was identified and no injuries were reported. It was unclear whether the sound the two individuals heard was a gunshot. Miller declined to speculate on what caused the sound.

About 100 people were working inside the center at the time, Miller said. Everyone got out safely.

Security forces didn't report their findings, but they expect to release more details during a press conference later on Friday. A time hasn't been released. A follow-up investigation is also planned Friday afternoon. Officials plan to talk with the individuals who reported the incident as well as look at security footage.

This story will be updated as more details become available.
