A former Army infantryman was killed on Monday after he opened fire outside a Dallas, Texas federal building.

Brian Isaack Clyde, was just outside the Earle Cabell Federal Building right before 9 a.m., according to NBC News. Dressed in tactical gear, Clyde exchanged fire with federal officers; after he was shot, he ran to a parking lot where he fell down. He was taken to a nearby hospital and pronounced dead. NBC also reported that police “conducted a controlled explosion” of his car.

No one else was injured in the shooting.

U.S. Army spokesman William Sharp confirmed that Clyde, a private first class, was an Army infantryman from August 2015 to February 2017.

Clyde posted a number of photos of himself in his Army uniform in 2015 and 2016, including one of a uniform (it's unclear who is wearing the uniform in the photo) with a 101st Airborne Division patch — which Clyde also appeared to be wearing on Monday.

His Facebook profile also says that he lives at Fort Campbell, which is home to the 101st.
