U.S. Air Force investigators have determined that post-traumatic stress disorder and the unraveling of a distinguished military career led an airman to fatally shoot his commander last year at a San Antonio base before killing himself, according to Air Force documents.
The April shooting at Joint Base San Antonio-Lackland prompted a lockdown and officials to abruptly end a nearby military training parade with thousands of spectators.
Investigators determined Tech. Sgt. Steven Bellino confronted Lt. Col. William Schroeder before the two struggled and Schroeder was shot multiple times. Both men were veterans of U.S. Special Operations Command.
