Active shooter call at Air Force base was false alarm

Rumble — Hours after a 911 call from the Wright-Patterson Medical Center prompted emergency responders in armored vehicles and unmarked cars to swarm the Air Force base, installation commander Col. Tom Sherman announced it had been a false alarm. There had never been a threat inside the on-base hospital. Instead, the still-unidentified 911 caller had mistaken an ongoing active shooter training exercise for the real thing.
