The Edmond post office shooting was a mass shooting that occurred in Edmond, Oklahoma, on August 20, 1986. In less than fifteen minutes, 44 year-old postal worker Patrick Sherrill pursued and shot several coworkers, killing 14 and injuring another six, before committing suicide. It is currently the deadliest workplace shooting in U.S. history, as well as the deadliest shooting by a lone gunman in the state of Oklahoma.
The attack, among other similar incidences of violence perpetrated by postal workers, inspired the American phrase “going postal”.
Background
Sherrill was a relief carrier, meaning he was often required to work alternate routes on different days, a position dictated by his rank on the seniority list. His lack of a permanently assigned route meant that he lacked the same job stability as other USPS workers. Opinions vary concerning his job performance. Some reports portray him as an erratic, irritable worker; others claim he performed well and was being badgered by management. In any case, on the afternoon of August 19, 1986, supervisors Esser and Bland reprimanded Sherrill for his behavior. Sherrill had threatened revenge twice out of anger towards being disciplined.
Shooting
On August 20, 1986, Patrick Sherrill armed himself with a mail bag containing three semi-automatic pistols along with ammunition and arrived at his workplace. Shortly after 7:00 a.m., he shot and killed Richard Esser Jr., one of two supervisors who had verbally disciplined him the previous day. Sherrill then sought out Bill Bland, another supervisor who had reprimanded him. However, Bland had overslept that morning and arrived an hour late to work, by which time the shootings were already over. Not finding Bland, Sherrill then killed co-worker Paul Michael Rockne, and sought more co-workers to kill.
At the time of the attack, around 100 workers occupied the facility. In total, Sherrill killed fourteen people and wounded six others. The shooting ended after Sherrill committed suicide by shooting himself in the forehead as police entered the facility.
