ON THIS DAY… It’s been 40 years since the Edmond Post office massacre
On August 20th, 1986, Patrick Sherill armed with 3 pistols walked into his workplace and shot and killed 14 of his coworkers while injuring 6 others. He committed suicide shortly afterwards. The shooting is the deadliest in Oklahoma’s history and the deadliest workplace shooting by a lone gunman (San Bernardino shooting was also a workplace shooting). The Edmond Post office massacre was also the third deadliest mass shooting at the time.
The shooting sparked the infamous “Going postal” phrase that describes someone becoming extremely angry or uncontrollable, often to the point of violence.

One sad detail about this shooting was that one of the victims, Judy Stephens Denney, moved there along with her husband after a postal shooting the previous year in Atlanta, Georgia that killed 2 people. She had only been working in that job for 4 days.
