A police watchdog has identified significant failings which led to the murder of Nicholas Churton by Jordan Davidson in 2017.
The Independent Office for Police Conduct said "ad hoc" information sharing between North Wales Police and the National Probation Services "significantly contributed to the sequence of events."
Nicholas Churton was killed with a machete and hammer at his Wrexham home in 2017 by Jordan Davidson, who had previous convictions but had been released from Parc Prison on licence.
North Wales Police officers responded to 8 incidents involving Davidson between his release from prison and the death of Mr Churton.
These incidents included arrests for theft, breach of peace and the possession of a bladed weapon.
Davidson was on police bail for a knife offence at the time of the killing.
The Independent Office for Police Conduct (IOPC) said North Wales Police, National Probation Service and the Community Rehabilitation services must improve information sharing.
The ad hoc liaison arrangements between North Wales Police and the CRC have significantly contributed to the sequence of events. There was no documented process, clear audit or specific guidance for those dealing with incidents involving Jordan Davidson and the decision to engage with the CRC was left to the discretion and experience of individual officers, with varying results.
The IOPC said a police sergeant will face a misconduct meeting for misconduct for "not carrying out adequate assessment of available information" prior the Davidson's release on bail.
North Wales Police said they accept the IOPC recommendations and will make "necessary organisational improvements."
The IOPC has, quite rightly, conducted thorough investigations into our interactions with the victim, Mr Nicholas Churton, and the offender, Jordan Davidson.
North Wales Police and Crime Commissioner Arfon Jones said he will work closely with the Chief Constable to deliver improvements.
This was a tragic incident and I would like to extend my sympathies to Mr Churton’s family.
This press release confirms what I feared – that systemic failings in our police and probation system led to the release of Jordan Davidson from police custody in March 2017, leaving him free to murder Nicholas Churton in his Wrexham home.
