Commenting on the murder, Head of Public Protection Branch Detective Chief Superintendent Lindsay Fisher, said: “Mary Ward is the fourth woman to be murdered in Northern Ireland in just six weeks.
“This is absolutely appalling. Four families have been shattered forever by meaningless violence.
“As a Police Service we recently revised our Tackling Violence against Women and Girls (VAWG) Action Plan and adopted the new national framework to align our response to this violence with that of terrorism and serious and organised crime.
“The level of violence and loss in Northern Ireland demands nothing less.
“We are absolutely determined that we will be relentless in our pursuit of the perpetrators.”
The case has also been referred to the Office of the Police Ombudsman, given prior contact between Ms Ward and the PSNI.
The police service added: “Whilst at this time there is no suggestion of individual criminality or misconduct, we are nonetheless concerned about our organisational response.”
