Mass murder and military aviation disaster. One community's experience with two fatal tragedies that occurred suddenly... but not without warning.

On 20 June 1994, a vengeance-seeking gunman opened fire in an Air Force hospital. Despite warnings from his roommates and co-workers. Despite the efforts of mental-health doctors. A sociopath had slipped through the cracks.

Four days after the shooting, a B-52 bomber crashed during an air-show practice flight. Aviators had complained about the rogue pilot and his reckless maneuvers. When leadership refused to ground him, they predicted the worst air-show disaster in history.

This compelling true story is told in the words of the people who witnessed the tragedies unfold--the heroes, the first responders, the victims and the survivors.

Written by Andy Brown, the Air Force cop who ended the killing spree. After seven years of research, Warnings Unheeded is part of his ongoing effort to share the story of two preventable tragedies and the lessons within.

How many times have you heard that a killer, "just snapped?" Or that a tragic "accident" was unpredictable?
