The Police Service of Northern Ireland (PSNI) has formally responded to the independent review conducted by Dr Jan Melia into the death of Katie Simpson and the subsequent investigation of Jonathan Creswell.

The review identified significant systemic failures within the police service, including a lack of professional curiosity, poor safeguarding practices, and a failure to recognise patterns of coercive control. Critically, the report highlighted that the PSNI failed to listen to individuals who raised early concerns regarding the circumstances of Katie's death.

Assistant Chief Constable Davy Beck, head of the Crime Department, issued a direct apology to Katie Simpson's family and acknowledged that those who raised alarms were proved right.

"The review makes clear that we missed opportunities. Warning signs were not fully recognised early enough and we did not listen to some of those who raised early concerns," ACC Beck stated. "Let me be clear, they got it right and we were too slow to respond to their concerns; that was wrong. Patterns of coercive control were not sufficiently understood or challenged, investigative decisions did not always reflect the level of professional curiosity and rigor that should have been applied."

He added: "The failings are clear, we fell short and for that, I am truly sorry." In response to the findings, the PSNI has outlined several structural and procedural changes already underway to prevent similar failings:

- Unified Command: The Criminal Investigation Department (CID) and Major Investigation Team (MIT) have been restructured under a single branch with a unified command of experienced Senior Investigating Officers.

- Enhanced Training: Mandatory training has been strengthened regarding coercive control, domestic abuse, and the necessity of an "investigative mindset."

- Supervisory Oversight: Death investigation instructions have been refreshed, and safeguarding referrals in domestic abuse cases are now subject to enhanced supervisory review.

- Resource Increases: As part of a dedicated recovery plan, the PSNI is committed to increasing resourcing within its Public Protection Branch.

ACC Beck emphasised that the police service is committed to implementing Dr Melia's recommendations in full, in partnership with the Department of Justice.

"Policing depends on public trust. When we do not meet the standards expected of us, particularly in cases involving vulnerable women and children, domestic abuse and safeguarding, that trust is damaged. It is our responsibility to rebuild it."

The PSNI also issued an appeal to anyone who may have been a victim of Jonathan Creswell, or any other perpetrator, urging them to come forward. ACC Beck concluded: "We are here to listen, to help and to keep you safe."
