Eight police officers are to face misconduct hearings over the handling of the case of a Derbyshire woman murdered by her former boyfriend.
Tania Moore was found dead in her car after being shot
Mark Dyche was jailed in 2005 for killing showjumper Tania Moore, 26.
The Independent Police Complaints Commission (IPCC) has investigated Derbyshire and Staffordshire Police after complaints from her family.
The Derbyshire Police officers will face a misconduct hearing scheduled to begin in October.
In 2005 Nottingham Crown Court heard that Dyche rammed Ms Moore's car off the road near her home in Alkmonton, Derbys, after a year-long hate campaign.
Following the complaints, the IPCC examined how Derbyshire and Staffordshire Police forces shared information before the murder and reviewed how Ms Moore's fears were treated.
Amerdeep Somal, IPCC commissioner for Derbyshire, said: "The death of a young woman like Tania Moore, who had her whole life ahead of her, was an absolute tragedy.
"Prior to her death, Tania had had significant contact with the police, and rightly expected to be protected from those who wished to harm her.
"I am satisfied that there is sufficient evidence for these officers to appear before a misconduct hearing and face charges that they neglected in their duty. We have investigated how this happened."
