Johnie Nichole Shadden was 26 and worked as a rural mail carrier on a route in Mason Valley, Nevada, about 75 miles southeast of Reno. She was shot and killed while on duty delivering mail at her own home; her husband, 27-year-old Dustin Cooper, initially reported the death to the Lyon County Sheriff’s Office as an accident.

A joint investigation by the Lyon County Sheriff’s Office, U.S. Postal Service inspectors, and the FBI lasted nine months and developed evidence inconsistent with an accidental shooting.

Neighbors and co-workers had known her as a regular, friendly presence on the route and the slaying overturned the early narrative of a tragic accident. If anyone knew Johnie, her movements that day, or saw anything unusual at the home or on the mail route, please share what can help clarify what happened.
