The case was first reported by Rolling Stone and comes at a time when the U.S. military is trying to purge its ranks of extremists and white supremacists.
At the time of his arrest, then-Air Force Sgt. Steven Carrillo was assigned to the 60th Security Forces Squadron, serving as a Phoenix Raven team leader.
One of two Ohio National Guardsmen arrested this spring for making terroristic threats has now been charged with illegally making and selling 3D-printed guns.
Authorities were first alerted to one of the airmen by social media posts he allegedly made between the 2020 presidential election and the attack on the U.S. Capitol.
Steven Carrillo, 33, changed his plea to guilty to a federal murder charge in the killing of David Patrick Underwood and to the attempted murder of Underwood’s colleague.
