The Police Service of Northern Ireland has confirmed that it is investigating three cases of suicide in the wake of the Katie Simpson case.

A report by the Police Ombudsman into the death of the County Armagh jumper found that the police investigation was she flawed and failed her family.

The report said there was “a general lack of investigative mindset”, which led to her death in 2020 being treated as a suicide for several months.

Jonathan Creswell was later charged with her murder.

Creswell was found dead at home aged 36 while on trial in April.

In a statement to BBC News NI on Friday, police said: “Following the Katie Simpson case, the Police Service of Northern Ireland are investigating three cases recorded as suicide.”

Ms Simpson, 21, from Tynan in County Armagh, was taken to hospital with serious injuries after an incident at a home in County Londonderry in August 2020.

Creswell, her sister’s partner, called 999 and pretended to find her hanging from a ladder.

But police later concluded that he beat her before strangling her.

Mrs Simpson was admitted to Altnagelvin Hospital, where she died six days later, never regaining consciousness.

Several red flags were missed before Creswell was ultimately charged with her murder.

The possibility of more such cases was raised by political representatives at a Police Council meeting in early September.
