Two police officers have been served with misconduct notices over their handling of a stalking allegation made by 23-year-old Gracie Spinks several months before she was killed, the police watchdog has said.
Spinks was stabbed to death in a field in Duckmanton, Derbyshire, in June as she was caring for her horse, and is believed to have been killed by Michael Sellers, 35, who was found dead nearby.
