A police officer who ignored reported stalking reports by a woman before she was murdered has been named.
Shana Grice, 19, reported her ex-boyfriend Michael Lane to Sussex Police five times in six months, but she was fined for wasting police time.
On 25 August 2016, Lane murdered Grice. He was jailed in 2017 for a minimum of 25 years.
Pc Jon Barry Mills left Sussex Police on May 10 after failing to "adequately investigate allegations of harassment and stalking, including a failure to review all possible evidence", the College of Policing said.
In an entry published on its Police Barred List this week, the body added that Mills "failed to respond to a report of harassment and stalking made by victim and failed to contact or update her regarding the reported incident".
The publicly accessible register includes details of all officers who have been dismissed over misconduct.
It is published to improve "integrity" and "accountability" as well as to "further the transparency" of the disciplinary system, the College of Policing said.
At a tribunal earlier this month, a reporting restriction was imposed which meant the constable was referred to only as Pc Mills to protect his "privacy".
Panel chairman Chiew Yin Jones said both allegations of gross misconduct were found to be proven against Mills and his actions may have "ultimately contributed in the circumstances which contributed to the tragic death of Ms Grice".
Had he not resigned, he would have been sacked, the panel said, as they barred him from ever working as a police officer again. But he can keep his pension.
On August 25 2016, Lane slit Shana's throat before trying to burn her body.
Shana had told officers she was too scared to leave her house as a result of Lane's stalking.
On July 9 2016, she rang police after discovering Lane had stolen a house key and crept into her bedroom while she slept.
He was arrested but Mills, an officer for 16 years, did not review case notes about their history before questioning him, even though he was experienced in interviewing suspects almost every day.
Mills questioned Lane for just 12 minutes before cautioning him, despite having attended a training course about stalking, harassment and interview techniques just a day earlier.
When questioned, he told the Independent Office for Police Conduct the case was not his priority and he found Lane's story "plausible" even though he was "alarmed" by his behaviour.
No-one from the force ever called Shana back after she reported Lane again days later on July 12 for following her in his car.
She stopped reporting him after that.
At the hearing the press were banned from reporting the officer's full name, with force lawyers saying it was "not in the public interest" to do so.
Pc Trevor Godfrey, who retired in December 2017, is due to face a public misconduct hearing after being accused of finding Shana to be "dishonest" and failing to "treat her as a victim, instead warning her about wasting police time".
Three more officers and three staff have already been handed "management advice and further training", while no further action will be taken over the other five officers investigated.
