Susan Tammy Hudson, 52, was not arrested, however, police said about 3.5 hours later.
It all started at about 12:24 p.m., according to a press release from the Kingsport Police Department.
That’s when KPD officers responded to 713 Union Hill Road after a call that a woman allegedly had shot and killed her husband.
Police said they were told Hudson had contacted her sister and told the sister she had shot and killed her husband.
When police arrived, contact was made with Susan Hudson, who told police it had been an April Fool’s Day joke.
Hudson’s husband, who was not involved with the joke, showed up shortly thereafter and was uninjured.
Shortly after 4 p.m., KPD said investigation of the incident continued.
