Johnathan Armstrong

Turnkey Johnathan Armstrong died after suffering a skull fracture while escorting a prisoner in the Madison County Jail.

He was taking the prisoner to a separate cell pending an investigation of his mental condition. He was holding the prisoner's arm when the man suddenly jerked away, causing Turnkey Armstrong to fall forward. His head struck a steel bar on the cell door and he suffered a skull fracture as a result. He died a short time later.

Turnkey Armstrong had served with the Madison County Sheriff's Department for one month. He was survived by his wife and parents.
