On this date in 1986, Postal Service employee Patrick Sherrill went on a shooting spree in a post office in Edmond, OK. Twenty people were shot, leaving fourteen dead and six injured. At the conclusion of his rampage, Sherrill turned the gun on himself and committed suicide. It is believed that the shooting may have been motivated by a reprimand that Sherrill had received the day before. The incident is often credited with inspiring the phrase “going postal.”
